It's time to say goodbye to California's most famous zip code (again). The CW is canceling 90210 after five seasons, with the series finale set to air this May. The show's ratings have been steadily dropping, and let's face it: Naomi, Annie, and the gang had a really good run, and lasted much longer than any of us expected them to. This news comes on the heels of the network's renewal of Arrow, The Vampire Diaries, and Supernatural, and now there's some breathing room for new shows like The Carrie Diaries. Will you miss the 90210 gang?
