Fiktiv USA - KRON-TV

KRON-TV, virtual channel 4 (VHF digital channel 7), is a MyNetworkTV-affiliated television station licensed to San Francisco, California, United States and serving the San Francisco Bay Area. The station is owned by Nexstar Media Group. KRON-TV maintains studios in the Western Addition section of downtown San Francisco, and its transmitter, shared with Fox O&O KTVU (channel 2) and CBS O&O KPIX-TV (channel 5), is located atop Sutro Tower in San Francisco.

KRON-TV is the second largest MyNetworkTV affiliate by market size that is not owned and operated by the Fox Television Stations subsidiary of Fox Corporation, which owns the programming service.

In the 1940s, when the channel 4 allocation in the Bay Area came open for bidding, it soon became clear that the license would go to either NBC or the deYoung family, publishers of the San Francisco Chronicle daily newspaper. NBC wanted an owned-and-operated station (O&O) in the Bay Area alongside its West Coast flagship radio station, KNBC (680 AM, now KNBR). However, in an upset, the deYoungs won the license. KRON-TV signed on the air on November 15, 1949, as a full-time NBC affiliate, operated alongside co-owned radio station KRON-FM (96.5, now KOIT-FM). The station's call letters come from a modification of the Chronicle's nickname, "The Chron". KRON-TV was the third television outlet in the Bay Area behind KGO-TV (channel 7) and KPIX-TV (channel 5), all going on the air within a year, and the last license before the Federal Communications Commission (FCC) placed a moratorium on new television station licenses that would last the next four years.

KRON-TV originally broadcast from studios located in the basement of the Chronicle Building at Fifth and Mission Streets. Newscasts benefited from the resources of the Chronicle and there was cooperation between KRON-TV and the newspaper. It originally maintained transmitter facilities, master control and a small insert studio on San Bruno Mountain. "NBC" lettering was placed near the summit of Radio Peak in huge white letters. In August 1959, the Chronicle reported that the tower was severely damaged by an unusually strong thunderstorm, requiring major repairs before KRON-TV could return to the air. In 1961, NBC attempted to purchase its own station in the Bay Area, when they attempted to buy KTVU. The sale was cancelled that October due to pre-existing concerns over the sale cited by the Federal Communications Commission (FCC) that were related to NBC's ownership of radio and television stations in Philadelphia; as a result, NBC stayed with KRON-TV.

In 1967, KRON-FM-TV moved to a new studio at 1001 Van Ness Avenue in the Western Addition neighborhood (a location that formerly served as the site of the Roman Catholic cathedral of San Francisco). The television transmitter was moved to Sutro Tower on July 4, 1973, while the FM transmitter remained on San Bruno Mountain.

Since the 1970s, KRON's logo has incorporated a stylized number "4" design that is based on the Golden Gate Bridge. The vertical component is a bridge tower, the horizontal component is a portion of the bridge deck, and the curve is a portion of a suspension cable. This logo was used as early as April 1974, during coverage of a Symbionese Liberation Army bank robbery. By about 1991, this evolved into the "circle 4" logo in use to this day, with the "4" keeping the bridge design.

In 1982, the deYoung family's Chronicle Publishing Company unit discussed a possible trade of KRON-TV to the Gannett Company (whose broadcasting division is now part of Tegna) in exchange for acquiring Gannett's Oklahoma City station KOCO-TV, plus an additional $100 million. The proposal ultimately fell apart by September 1983.

On June 16, 1999, the deYoung family announced the liquidation of Chronicle Publishing's assets. By this point, the deYoungs owned three television stations (including KRON) in large and mid-sized media markets around the country, two of which were sold off to LIN TV (which traded KAKE-TV in Wichita and WOWT in Omaha to Benedek Broadcasting in turn). The San Francisco Chronicle, meanwhile, was acquired by the Hearst Corporation in a $295 million deal in October of that year.

NBC had made many offers for channel 4 over the years, but the deYoungs turned them down each time. It finally saw the opportunity to get an owned-and-operated station in what was then the United States' fifth-largest television market and quickly jumped into the bidding war for KRON. NBC was seen as the frontrunner to buy the station, but it was outbid at the last minute on November 16, 1999. KRON was bought by New York City-based Young Broadcasting, then-owner of Los Angeles independent station KCAL-TV and several other stations in medium to small markets. Young's purchase price for the station ($750 million at the outset, rising to $820 million by closing) was a record price for a single station that stands to this day. To help finance the down payment, Young was forced to sell La Crosse, Wisconsin, CBS affiliate WKBT to Morgan Murphy Media.

NBC president and chief executive officer Bob Wright had warned that if NBC did not succeed in buying KRON, it would require any prospective buyer to uphold specific terms if it wanted to retain the NBC affiliation. Wright did not rule out moving NBC's Bay Area affiliation elsewhere. When Young closed on its purchase of channel 4, NBC made good on these threats by demanding that Young operate KRON under the same conventions as an NBC owned-and-operated outlet. Among other things, it demanded that KRON change its on-air name to "NBC 4" and run the network's entire schedule in pattern (reducing primetime preemptions due to local programming from 20 hours to five hours a year). Preemptions would only be permitted for extended breaking news or severe weather coverage. NBC also demanded yearly payments of $10 million from Young, a form of reverse compensation, flipping around the then-normal mode of networks paying their affiliates for their airtime. (In turn, NBC would stop making annual payments to KRON of $7.5 million to carry the network's programming.) Young would also have to give NBC the first option on the programming of additional subchannels on the station's digital signal.

Rather than give in to NBC's demands, Young decided not to renew channel 4's affiliation contract, which was set to expire at the beginning of 2002. San Jose-based KNTV channel 11 approached NBC with a proposal to pay $37 million annually for the rights to broadcast its programming. In 1999, KNTV joined The WB in conjunction with the network's existing Bay Area affiliate, then co-owned KBWB (channel 20, now KOFY-TV). KNTV agreed to drop its ABC affiliation at the behest of network-owned KGO-TV, the market's primary ABC station. NBC accepted KNTV's deal in February 2000. It did so primarily as a stopgap in case NBC failed in its bid to buy KRON from Young.

However, Young's asking price for the station was $735 million, only slightly less than what it paid to buy the station from Chronicle. NBC felt that price was too high, and walked away from the deal when Young refused to lower it. In December 2001, NBC purchased KNTV from Granite Broadcasting for a fraction of KRON's sale price of $230 million. That made NBC the only major broadcast network to have switched from one Bay Area station to another. The last NBC program to be broadcast by channel 4 was a repeat episode of Crossing Jordan, at 10:00 p.m. on December 31, 2001. KNTV officially joined NBC later that evening at 11:35 p.m. with the regular broadcast of The Tonight Show with Jay Leno. That ended KRON-TV's 52-year affiliation with the NBC network.

With ABC, CBS, UPN and now NBC carrying their programming locally on owned-and-operated stations (KGO-TV, KPIX, KBHK—channel 44, now KBCW—and KNTV respectively), and Fox and The WB under contract with KTVU and KBWB respectively, KRON-TV became an independent station by default. The station filled time slots formerly occupied by NBC shows with syndicated programming and expanded newscasts. The NBC Network was near the top of the ratings nationally at the time of the disaffiliation, due to strong shows such as Friends, Frasier, Law & Order and ER. Without those NBC shows, KRON's ratings started to decline. The viewership of its newscasts began to fall substantially by the time the station regained a network affiliation.

On February 22, 2006, News Corporation announced the launch of MyNetworkTV. The network was created partly in response to CBS Corporation and Time Warner's January 24 announcement that UPN and The WB would be shut down and replaced with the jointly-owned CW Television Network. (CBS-owned UPN affiliate KBHK, whose call sign became KBCW by the network's launch, was named The CW's Bay Area affiliate. WB affiliate KBWB became an independent station). KRON-TV became a MyNetworkTV affiliate when it debuted on September 5, 2006. (It is currently one of the largest MyNetworkTV-affiliated stations not to previously have been an affiliate of either The WB or UPN, second only to the network's Dallas O&O KDFI.)

KRON began branding itself as "MyKRON 4" for MyNetworkTV programming, although it continues to promote itself as "KRON 4" outside of the service's programming hours. After joining MyNetworkTV, the station moved its hour-long 9 p.m. newscast to 8 p.m. It chose to run the fledgling network's programming from 9 to 11 p.m., one hour later than MyNetworkTV's standard 8 to 10 p.m. scheduling in the Pacific Time Zone. Currently (December 2020), MyNetworkTV programming airs from 11:35 p.m. to 1:35 a.m.

On January 10, 2008, Young Broadcasting announced it would sell KRON-TV. The company had been encountering difficulties in meeting interest payments on its outstanding debt. Young's stock, which had been trading for a few cents per share, was ultimately delisted from NASDAQ in January 2009, after failing to meet the minimum standards for being on the exchange. One month later on February 13, Young made a filing to place the company under Chapter 11 bankruptcy protection. Debt incurred from its 1999 purchase of KRON was believed to be one key factor behind the company's cash problems. Young originally hoped to close a sale of the station by the end of the first quarter of 2008, but no buyer emerged.

On February 13, 2009, the company declared Chapter 11 bankruptcy. At the last minute, Young cancelled a planned auction of all 10 of its stations five months later on July 14, a move believed to have been made due to a lack of suitable bids. Instead of auctioning off the stations, Young and its secured lenders reached a deal where the lenders (among them Wachovia and Credit Suisse) would take control of the company, and Gray Television would manage seven of Young's ten stations. KRON, WATE-TV in Knoxville, Tennessee, and WLNS-TV in Lansing, Michigan (the latter two, unlike KRON, compete with Gray-owned stations in their respective markets), were the only stations not included in the management deal.

In February 2010, Young discussed the possibility of entering into a shared services agreement (SSA) with KNTV's owner NBCUniversal. That year, KRON informally reunited with NBC as it began to carry network programs during sports programming and breaking news events that force their preemptions on KNTV. (This responsibility as a backup NBC affiliate was assumed by KICU-TV in 2012.)

On June 6, 2013, Media General announced it would acquire Young Broadcasting in an all-stock deal. The merger was completed on November 12, 2013. The move made KRON-TV the largest station by market size owned by Media General as well as the company's only station west of the Rocky Mountains. (Most of Media General's television stations were in the Southeastern, Midwestern and Northeastern United States.)

In June 2014, Fox Television Stations announced it would acquire KTVU and KICU-TV in a trade with Cox Media Group in exchange for that company's stations in Boston and Memphis. Prior to the announcement it was rumored that Fox had considered buying KRON-TV and moving Fox network programming to channel 4. (Had Fox actually acquired KRON-TV, this would have made it one of the two major networks in the Bay Area, along with NBC, to switch from one station to another.) Fox completed its acquisition of KTVU and KICU-TV on October 8, 2014; despite MyNetworkTV being operated by Fox Television Stations, as of 2020, KRON-TV remains an affiliate of the network.

On January 27, 2016, Nexstar Broadcasting Group announced that it had reached an agreement to acquire Media General. The transaction was consummated on January 17, 2017, and with it, KRON became part of the Nexstar Media Group.

Until the late 1970s, KRON-TV was known for being very San Francisco-centric in its news coverage and audience targeting, an approach that would become costly to the station as population growth in areas outside San Francisco soared. Realizing this and refocusing on the entire market enabled KRON-TV to become the dominant station in the Bay Area.

During the 1980s, KRON continued its dominance by airing top-rated syndicated programs, including the Merv Griffin-produced game shows Jeopardy! and Wheel of Fortune (the original NBC daytime versions of both series also aired on KRON), as well as Entertainment Tonight. The game show pair would move to ABC-owned KGO-TV permanently in 1992 after KRON-TV experimented with its "early prime time" schedule that year, while ET also moved to KGO in 1988, before returning to KRON in 1992 (where the show has remained since).

Other syndicated programming currently airing on KRON-TV includes Dr. Phil, Inside Edition and The Doctors.

During the 1992–1993 season, KRON-TV, along with KCRA-TV, participated in the "Early Prime" experiment in which prime time programs aired one hour earlier (mirroring the scheduling of the network's primetime lineup in the Central and Mountain time zones), the half-hour late evening newscast also moved from 11:00 to 10:00 p.m. as a result. While KRON moved NBC's prime time programming back to the 8:00–11:00 p.m. timeslot in September 1993, CBS affiliate KPIX, who adopted the early primetime schedule at the same time as KRON, continued with the experiment until 1998–well after it had become owned by the network through CBS's 1994 acquisition by KPIX's then-owner Westinghouse. Though both KRON and KPIX ran hour-long newscasts at 10 p.m., neither were able to beat Fox affiliate KTVU, due to that station's longtime dominance in the 10 o'clock hour that continues to this day.

In 1965, KRON-TV began broadcasting most Oakland Raiders games, which were at first part of the American Football League, which had a contract with NBC from 1965 to 1969, and then the National Football League's American Football Conference, which inherited the AFL's deal with NBC from 1970 to 1997 (the Raiders relocated to Los Angeles in 1982, stripping KRON of its status as the team's home station until they returned to Oakland in 1995; the station then served as the unofficial home station until 1997). KRON aired coverage of the Raiders' victories in Super Bowl XI and Super Bowl XV. In 2020, KRON-TV became the now Las Vegas Raiders official Bay Area home station for pre-season games and special programming.

In addition, during those same years (1970–1997), KRON-TV also aired select San Francisco 49ers games whenever they played host to an AFC opponent at Candlestick Park (the station aired the team's victory in Super Bowl XXIII in January 1989).

In 1993, Channel 4 became the flagship station of the Oakland Athletics, after acquiring broadcast rights to the Major League Baseball team's games. This caused a problem in 1996, when the final day of the U.S. Olympic track and field trials conflicted with a scheduled Athletics broadcast. Since KRON-TV was contractually obligated to show the baseball game live, it rebroadcast the trials at midnight. KRON lost the Athletics' television rights following the team's 1998 season. Both select Oakland A's and San Francisco Giants games were aired as part of NBC's broadcast contract with Major League Baseball from 1957 to 1989, including the A's string of three consecutive World Series victories in 1972, 1973, and 1974.

Since 1989, KRON-TV produces a countdown program called New Year's Live, which airs on New Year's Eve (sometimes beginning at 11 p.m.) and continues into New Year's Day (sometimes ending at 1 a.m.). Events in San Francisco are the focal point of KRON's coverage, especially the midnight fireworks show near the Ferry Building. Other West Coast television stations joined KRON in some years (including KCAL-TV/Los Angeles, KING-TV/Seattle, KCRA/Sacramento, KNSD/San Diego and KLAS-TV/Las Vegas in December 1990), featuring midnight countdown events in other cities, such as Las Vegas casinos and at the Seattle Space Needle. Former KRON weather anchor Mark Thompson served as the host during the program's early years.

KRON-TV also produces two locally-produced programs outside of local newscasts: Bay Area Living – Home Improvement Edition and Bay Area Bargains. Past local programs include Bay Area Backroads, Bay Cafe, Henry's Home & Garden, Latin Eyes, Pacific Fusion, The Silver Lining; and several series and featured news segments that were developed by Jim Swanson, executive producer including Bay Area Bargains – Green Edition; Bay Area Living – Seniors Edition; KRON 4's Body Beautiful; KRON 4's Casino Adventures; Don't Invest and Forget; Health and Beauty with Dr Sonia; Living Green with Petersen Dean; KRON 4's Medical Mondays; KRON 4's Peninsula Beauty; KRON 4's Sizzling Hot Auto Deals and KRON 4's Spa Spectacular.

As of 2020, KRON presently broadcasts 78½ hours of local newscasts each week (with 13½ hours each weekday and 5½ hours each on Saturdays and Sundays). With regards to the number of hours devoted to news programming, it is the highest newscast output of any television station in the San Francisco Bay Area.

KRON's news operations were handled by the Chronicle until it launched its own news department in September 1957. It operated from a studio inside the Chronicle building at Fifth & Mission streets (the station's news department was located 30 feet from the Chronicle city desk). Appropriately for a station once owned by the Chronicle, KRON-TV has long been a very news-intensive station. it produced six daily newscasts at the time, including the Shell-sponsored 6 p.m. newscast Shell News, with Tom Franklin reporting from the studio at the Chronicle and in filmed field reports. Franklin began the broadcast standing next to a map of the San Francisco Bay Area, with lights illuminated on the map next to the various cities that the newscast was to feature stories from. Franklin anchored most of the program from behind a desk that had a large Shell logo next to a "Tom Franklin" nameplate, with a Shell "X-100" oil can that sat atop the desk. Live segments were used for late bulletins from the Chronicle city desk or for local and regional stories not suitable for film treatment. Some of the stories covered by Shell News in 1957 included the end of the "pedestrian scramble" system at downtown San Francisco street intersections, the end of the San Francisco-Oakland Southern Pacific railroad passenger ferry and the final game of the San Francisco Seals baseball team (to be replaced by the San Francisco Giants in 1958). In the 1960s, KRON-TV had anchors Art Brown and Jerry Jensen (who later moved to KGO-TV), and Linda Richards, who wrote predicted temperatures backwards on sliding glass panels with maps drawn on them, for viewers to see the weather forecast. Ed Hart, and later Frank Dill, reported sports with a focus on only the area's professional teams. KRON's early morning news digests in the 1960s utilized sign language by Peter Wechsberg and Jane Norman.

KRON-TV eventually branded its newscasts as Newswatch 4 in the early 1970s. By early 1972, the station ran newscasts at noon, 5:30, 6:30 and 11 p.m. on weekdays and 6 and 11 p.m. on weekends, it also ran a late newscast that aired (then) immediately after The Tonight Show called the Newswatch Sign-Off Edition. Presenters then included Terry Lowry, Phil Wilson, Karna Small, Bob Marsden, Paul Ryan, Art Brown and Dave Valentine. The station's newscasts were branded as NewsCenter 4 from 1977 until 2001, when it was changed to the current KRON 4 News. A major change in KRON-TV's evening news broadcasts occurred on April 6, 1981, when the station launched the 90-minute newscast "Live on 4" (from 4 to 5:30 p.m.). NBC Nightly News also moved from 7 to 5:30 p.m. (KPIX and KGO would follow this move with their national newscasts during the following decade). From late 1981 to late 1988, the 5 p.m. weekday newscast was Live at Five; Bob Jimenez anchored in the studio with Evan White in the newsroom. Live on 4 was replaced in 1983 with T.G.I.4, an hour-long light local news and interview program co-hosted by Jan Rasmusson and Patrick Van Horn. In the mid-1980s, KRON-TV produced and aired an afternoon talk program called Bay City Limits.

In 1981, KRON launched its first morning newscast with a seven-minute program (at 6:53 a.m.), the program was cancelled by late 1982. All the evening newscasts featured a variety of anchors, until settling down with the successful duo of Roz Abrams and Jim Paymar. After Abrams left for New York City's WABC-TV in 1986, Paymar co-anchored alongside Sylvia Chase (who had been a correspondent for CBS News and later for the ABC newsmagazine 20/20). The station debuted what was then the only local early morning newscast in the San Francisco television market on September 1, 1986, with the launch of Daybreak (which ran from 6:30 to 7 a.m., leading into Today). The first anchors were Lloyd Patterson and Lila Petersen.

KRON's newscasts during the 1980s regularly featured commentaries by Wayne Shannon in a segment called "Just 4 You", many of which had a humorous tone. Shannon received billing in newscast introductions along with the anchors, and weather and sports presenters. Another staple of KRON-TV newscasts in the 1980s was live traffic reports and news coverage from the station's helicopter "Telecopter 4." Bob McCarthy, Rita Cohen and Janice Huff were among the personalities who reported from Telecopter 4. Their traffic reports appeared regularly on Daybreak, during Today and Live at Five. Evocative of his folksy, down-to-earth style, McCarthy had a catchphrase, "hunky snarky", that he often used to characterize roads on which traffic was flowing smoothly. Will Prater was the main pilot of Telecopter 4 in its early years and Lou Calderon was the main photographer. KRON also broadcast from remote locations during this era (e.g., Super Bowl venues) via a satellite uplink unit dubbed "Newstar 4". These segments often began with an animation depicting a signal originating from the uplink location, bouncing off a satellite and ending at a satellite dish next to the words "San Francisco." KRON-TV regarded the satellite truck as a major competitive advantage over rival television stations, featuring it in a mid-1980s promotional spot which declared, "We got a mobile satellite up-link. They don't."

In the 1980s, KRON-TV produced lengthy analysis pieces for the "Cover Story" segment on its 6 p.m. newscast, many with an investigative journalism focus and sometimes produced by the 10-person "Target 4" investigative unit. The station reran some of these segments in an occasional program called Cover Story Magazine. The station also produced a half-hour public affairs program on Sunday mornings called Weekend Extra, which was hosted by Belva Davis and Rollin Post. This program frequently presented features from KRON's news bureaus in Washington, D.C. and Sacramento, the only Bay Area station to maintain bureaus (which were later deemed to be too expensive and were shut down by the end of the decade). During this time, KRON news grew rapidly in viewership and collected a large number of awards, including two DuPont Columbia awards, a Peabody, and more than 100 local Emmys. The station also produced a series of one-minute documentaries during the mid-1980s, San Francisco Minutes and Bay Area Minutes, which featured people, places and events in San Francisco and Bay Area history and usually featured narrations by KRON-TV personalities set to soaring music (e.g., Mark Thompson on San Francisco's cable cars, Lloyd Patterson on the San Mateo County coastline).

In the 1990s, the station utilized a "24 Hour News" format, with 30- to 60-second news updates each hour outside of regular newscasts. During the May 2001 sweeps period – its last as an NBC affiliate – KRON's newscasts beat KGO-TV's in the 5 and 6 p.m. timeslots by a very close margin, ending KGO's domination in those timeslots. When KRON lost NBC to KNTV and became an independent station in January 2002, the station expanded its news programming by adding two hours to its weekday morning newscast (from 7 to 9 a.m.), and extending its 6 p.m. newscast to one hour to fill timeslots vacated by the departures of Today and Nightly News.

Unlike most news-producing stations that have become independent after losing a network affiliation or that have switched to one of the post-1986 broadcast networks, KRON originally kept its late newscast in the 11 p.m. timeslot instead of moving it to or adding one at 10 p.m. (avoiding direct competition with KTVU's long-dominant primetime newscast, though KRON's late news remained in competition against KGO, KNTV and KPIX's late evening newscasts); the station also added a primetime newscast at 9 p.m. To this day, KRON maintains a newscast schedule similar to the one it had as an NBC affiliate. It is the only MyNetworkTV affiliate that has ever maintained a news schedule mirroring that of a Big Three affiliate (as it carries morning, 5 p.m., and 6 p.m. newscasts, and an 11 p.m. newscast). Several of KRON's veteran anchors and reporters left the station after the loss of the NBC affiliation; KRON also began incorporating video journalists (many of which were newer hires) to report, tape and edit news stories.

On September 17, 2007, KRON-TV became the third station in the Bay Area (behind KGO and KTVU) to begin broadcasting its local newscasts in 16:9 widescreen—albeit in standard definition. In September 2008, KRON dropped its 5 p.m. newscast after the syndicated daytime talk show Dr. Phil was moved to the slot, the program's former 8 p.m. timeslot (which Dr. Phil held locally since the show's 2002 premiere) was replaced by an hour-long primetime newscast; this would be undone in September 2009, with the cancellation of the 8 p.m. newscast and Dr. Phil's return to the 8 p.m. slot, along with the reinstatement of a 5:30 p.m. newscast (which expanded back to 5 p.m. by 2010). The 8 p.m. newscast returned in September 2011, concurrent with the replacement of the 4 p.m. news with Dr. Phil. KRON quietly upgraded its newscasts to high definition in April 2012, with the debut of new graphics. As of September 2013, only studio segments and on-air graphics are presented in HD, footage from field cameras and other news sources continue to be broadcast in widescreen SD.

KRON launched a new 10 p.m. newscast on May 16, 2016, that competes with newscasts on KTVU and KBCW. Also at that time, KRON reinstated the hour-long weekday 12 p.m. newscast. The station launched a new 9 p.m. newscast on August 21, 2017, which competes with KGO's 9 p.m. newscast for KOFY-TV. On September 14, 2020, KRON reinstated an hour-long 4 p.m. newscast on weekdays.

KRON-ON is a 24-hour regional cable news channel that serves the San Francisco Bay Area. The channel is owned by Nexstar Media Group. It was originally owned as a joint venture between the locally based Chronicle Publishing Company (which owned a controlling 51% interest) and cable provider Tele-Communications, Inc. (which owned the remaining 49% share). The channel operates from KRON-TV's studio facilities in the Western Addition section of downtown San Francisco.

The channel launched on July 1, 1994 as BayTV, operating as companion service to NBC affiliate KRON-TV (now a MyNetworkTV affiliate). The company was founded by the San Francisco-based Chronicle Publishing Company, in conjunction with Tele-Communications, Inc. (TCI), which carried it on cable channel 35 throughout the provider's San Francisco-Oakland-San Jose service area, and its affiliate company Liberty Media. When BayTV debuted, its programming primarily consisted of rebroadcasts of KRON-TV's news programs, as well as some limited news and talk content exclusive to the channel (including the morning newscast BayTV Morning and a video simulcast of KRON sports director Gary Radnich's midday sports talk show on KNBR (680 AM), The Gary Radnich Show). The channel originally utilized equipment formerly used by its parent station, with a separate staff of writers and producers.

On June 16, 1999, the deYoung family announced their intention to liquidate Chronicle Publishing's assets, including KRON-TV (as well as sister stations KAKE-TV in Wichita and WOWT in Omaha, which were both sold to Benedek Broadcasting), BayTV and the San Francisco Chronicle (which it sold to the Hearst Corporation for $295 million in October of that year). Around the same time, TCI's minority share in BayTV was sold to AT&T Corporation, as part of the company's acquisition of the provider (which became AT&T Broadband). KRON and Chronicle's majority interest in BayTV were purchased by New York City-based Young Broadcasting for US$737 million cash and $13 million in stock (rising to $823 million by the sale's closure) on November 16, 1999. The transaction was supposed to be completed by April 2000, however finalization of the deal was delayed by two months after former Chronicle editor Clint Reilly filed a lawsuit to block the Hearst Corporation's purchase of the newspaper.

On February 10, 2001, KRON station management decided to consolidate BayTV's news department with that of KRON.

On January 10, 2008, Young Broadcasting announced it would sell KRON-TV and BayTV. The company had been encountering difficulties in meeting interest payments on its outstanding debt. Young's stock, which had been trading for a few cents per share, was ultimately delisted from NASDAQ in January 2009, after failing to meet the minimum standards for being on the exchange. One month later on February 13, Young made a filing to place the company under Chapter 11 bankruptcy protection. Debt incurred from its 1999 purchase of KRON and BayTV was believed to be one key factor behind the company's cash problems. Young originally hoped to close a sale of the station by the end of the first quarter of 2008, but no buyer emerged.

On February 13, 2009, the company declared Chapter 11 bankruptcy. At the last minute, Young cancelled a planned auction of all 10 of its stations and BayTV five months later on July 14, a move believed to have been made due to a lack of suitable bids. Instead of auctioning off the stations, Young and its secured lenders reached a deal where the lenders (among them Wachovia and Credit Suisse) would take control of the company, and Gray Television would manage seven of Young's ten stations. KRON, BayTV, WATE-TV in Knoxville, Tennessee, and WLNS-TV in Lansing, Michigan (the latter two, unlike KRON, compete with Gray-owned stations in their respective markets), were the only stations not included in the management deal.

On June 6, 2013, Media General announced it would acquire Young Broadcasting in an all-stock deal. The merger was completed on November 12, 2013.

On February 10, 2014, Media General announced that KRON-TV and BayTV would move into leased space on the third floor of KGO-TV's building (ABC Broadcast Center) at 900 Front Street, in space formerly occupied by radio stations KGO and KSFO. KRON-TV's studios at 1001 Van Ness Avenue would be put up for sale. Despite the co-location, KRON-TV and BayTV maintain separate broadcast facilities from KGO-TV and employ a completely separate staff. Each station's employees are restricted by keycards from entering the other's facilities.

On January 27, 2016, Nexstar Broadcasting Group announced that it had reached an agreement to acquire Media General. The transaction was consummated on January 17, 2017, and with it, BayTV became part of the Nexstar Media Group.

On February 25, 2019, BayTV was renamed KRON-ON, aligning it further with the call letters of its broadcast station KRON-TV.

KRON-ON is the Bay Area's first local 24-hour news and information channel. KRON-ON was created in response to the Bay Area's continued demand for more local news and to expand and focus news coverage on a uniquely local level to augment its long tradition of serving the community needs.

With news bureaus in San Francisco, Oakland and San Jose, KRON-ON is a Bay Area wide station. Reports generated from Oakland and South Bay bureaus typically represent one-third of the total news stories covered.

With KRON-ON, the KRON 4 newsroom delivers relevant breaking news, live events and press conferences, as well as up-to-the-minute weather and traffic coverage twenty-four hours a day, seven days a week.

KRON-ON features 13 and a half hours of KRON regularly scheduled live, local news programming and content, including six hours of live morning news coverage and six and a half hours of live evening news.

The channel delivers even more local content to Bay Area viewers with live bonus coverage during standard broadcast commercial breaks. Once KRON 4’s live broadcast programming concludes, KRON-ON continues with exclusive local content, feature stories, news, weather, traffic and much more 24/7.

The channel also delivers original live local programming exclusive to KRON-ON, including Next Step, a half-hour Silicon Valley-focused technology newsmagazine and Bay Area Sports Night, a one-hour sports talk program weeknights at 7:00pm hosted by KRON sports director, Mark Carpenter.
