TNBC

TNBC (or Teen NBC) is the name of a former American teen-oriented television programming block that aired on NBC from September 12, 1992 to September 28, 2002, due to its replacement with the children's-oriented Discovery Kids on NBC educational lineup. The Saturday morning block featured comical live-action series – primarily in the form of scripted sitcoms and variety series such as Saved by the Bell, California Dreams, Hang Time, One World, City Guys and others – geared toward teenagers and sometimes young adults, the majority of which were produced by such key people as Peter Engel and the network's in-house production units NBC Studios and NBC Enterprises.

History
As early as 1988, NBC had been openly contemplating replacing its Saturday morning cartoon programming block of children's animation with less expensive, in-house programming oriented towards older audiences, such as talk shows and travel-themed programs, due to increasing competition from weekday afternoon cartoons airing in first-run syndication. The idea for a block specifically oriented towards a teenage demographic sprang from the popularity of the teen sitcom Saved by the Bell, which centered on a group of six students attending the fictional Bayside High School in Pacific Palisades, Los Angeles. Debuting on the network's Saturday morning lineup in September 1989, Saved by the Bell was a re-imagining of the sitcom Good Morning, Miss Bliss, which originated on The Disney Channel, a pay-TV channel in 1988 (the predecessor series served as a starring vehicle for Hayley Mills, who unlike fellow series regulars Mark-Paul Gosselaar, Dennis Haskins, Lark Voorhies and Dustin Diamond, did not return for the retooled series).

In 2000, Just Deal became the first TNBC scripted series not to be produced by Peter Engel since the1993 series Running the Halls, and the first series to be shot in a single-camera format. The following year, Sk8 premiered on the block, lasting for one season before being canceled. Both Just Deal and Sk8 were productions of Thomas W. Lynch, who had previously produced several hit teen dramas for Nickelodeon. By 2001, the block was suffering from declining viewership, particularly among its intended audience of teens; much of its audience by this point was from older viewers who had left their TV on after Weekend Today ended, and by its last season, the average age of a TNBC viewer was 41 years old.

NBC shut down the program block in 2002, leasing out its children's programming to Discovery Kids in a brokered programming arrangement. NBC blamed TNBC's failure on the network's poor performance among younger viewers in its regular prime time program lineup, leaving no opportunity to promote children's programming there; the network would have abandoned children's programming altogether if not for the E/I mandates.

Return
On June 29, 2023, NBCUniversal announced it would revive the TNBC brand for a free ad-supported streaming television channel to launch on Amazon Freevee and Xumo Play later that summer. Debuting as part of a larger slate of FAST channels featuring content from the NBCUniversal library, the channel will include reruns of programming from the TNBC block, as well as other sitcoms such as Punky Brewster and Major Dad. On May 31, 2024, it was announced that TNBC would be rebranded the next day as NBC Comedy Vault.
