The fifth and final season of 90210 was announced on May 3, 2012.[2][3] On May 17, 2012, it was announced that the show's fifth season would be moving back to Mondays at 8:00pm Eastern/7:00pm Central followed by the sixth season of Gossip Girl at 9:00pm.[4] The season premiered on October 8, 2012.[5]
90210 went on its mid-season break on December 10, 2012, and returned on January 21, 2013, at a new time slot of 9:00 pm, one week after The Carrie Diaries' premiere, which took its original time slot of 8:00 pm.[6]
On January 13, 2013, the President of The CWMark Pedowitz stated that although 90210 does not 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.[7] 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.[8]
