90210 (season 5)
On January 13, 2013, the President of The CW Mark Pedowitz stated that although "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 long-running shows. In spite of this, in late February it was announced that the fifth season would indeed be the final season of the show, with the series finale airing May 13, 2013.On June 30, 2012, The CW released the first promotional ad for the fifth season. However, no new scenes featured in the 30 second ad, but rather recapped the final episode of season four. On August 23 at the 90210 launch party for season five, a new 30 second ad was released, showing brand new scenes of the upcoming season, including Justin Deeley's scenes. The CW then released another brand new promo for the fifth season on 11 of September, featuring more new scenes form the upcoming premiere, and brand new graphics for the shows promotional campaigns. On September 27, 2012, the cast and crew celebrated their 100th episode in Manhattan Beach, California.
