Rosie O'Donnell | 'The Rosie Show,' 2011

On air for: One season. Cause of cancellation: O'Donnell exited with extreme gratitude to the OWN Network after her show was canceled due to low ratings: "Oprah [Winfrey] gave me an amazing shot at doing this. She really did. She put me back on TV. She believed in me," she said from the show's Chicago set in a video posted on YouTube. O'Donnell added that her attempt to re-create her Emmy-winning talk show from the 1990s fell flat. Most memorable moment: After an on-air fallout with co-host Elisabeth Hasselbeck on "The View" and a seething memoir that followed, a toned-down O'Donnell returned to television in a classy way. Where she is now: O'Donnell is still involved in R Family Vacations, a vacation entertainment company that caters to the LGBT community.
