90210 (TV series)
On January 13, 2013, the President of The CW Mark Pedowitz stated that though "90210" doesn't have a season 6 renewal in place, the show would most likely be back next year (possibly for the final season if it were to be canceled) due to him being a "big believer in giving fans a very satisfactory conclusion" for a long-running show. However, on February 28, 2013, The CW Entertainment President, Mark Pedowitz, announced that "90210" would end its run after five seasons and 114 episodes.
Fox Broadcasting Company
As Fox gradually headed towards carrying a full week's worth of programming in prime time – through the addition of programming on Thursday and Friday nights at the start of the 1990–91 season – the network's added offerings included the scheduling of "The Simpsons" opposite veteran NBC sitcom "The Cosby Show" as part of Fox's initial Thursday night lineup that fall (along with future hit "Beverly Hills, 90210", which would become the network's longest-running drama, airing for ten seasons) after only a half-season of success on Sunday nights. The show performed well in its new Thursday slot, spending four seasons there and helping to launch "Martin", another Fox comedy that became a hit when it debuted in August 1992. "The Simpsons" returned to Sunday nights in the fall of 1994, and has remained there ever since.
