Fiktiv USA - NBC Lx

Lx (formerly NBC Nonstop) is an American free-to-air television network owned by the NBC Owned Television Stations division of NBCUniversal. The network features a mix of news and lifestyle programming. The network is carried on the digital subchannels of eleven owned-and-operated stations of the NBC television network.

After NBCUniversal shut down NBC Weather Plus in December 2008 (shortly after the company, along with Blackstone Group and Bain Capital, purchased The Weather Channel), the company's flagship WNBC in New York City replaced Weather Plus' successor, automated local weather service, NBC Plus, on digital subchannel 4.2 on March 9, 2009, with NBC New York Nonstop, a channel that featured a mix of locally produced news and lifestyle programming.

In June 2010, NBC Local Media appointed former WNBC General manager Tom O'Brien in the newly created position of Executive vice president of Nonstop Network. In October, WNBC sister stations WCAU and WRC-TV respectively launched their own versions of the Nonstop channel in the Philadelphia and Washington, D.C. markets. Chicago's WMAQ-TV launched its own local version in November 2010. NBC's three owned-and-operated stations in California (KNBC in Los Angeles, KNTV in San Jose, California-San Francisco and KNSD in San Diego) collaborated to launch the only regional Nonstop channel, NBC California Nonstop, in January 2011; Nonstop channels were also launched by KXAS-TV in Dallas-Fort Worth, Texas, WTVJ in Miami and WVIT in New Britain, Connecticut that same month. On January 1, 2017, WBTS-CD launched its own version of the channel after it became the market's NBC affiliate.

On September 23, 2019, NBC Nonstop was rebranded as Lx. The name is short for Local X with the X standing for "exponential". On that same day, the network launched a digital news brand featuring “visually rich,” longer-form content targeting the younger demographic.

The subchannel carries thirteen hours of locally-produced programming (usually in the form of additional local newscasts exclusive to the subchannel and some lifestyle or talk-oriented programs), along with core programming from affiliated production company LXTV (such as Talk Stoop, First Look and Open House) as well as additional content from Jukin Media, Tastemade and the Dodo.
