You are so wrong. Her show Ellen was on for at least 4 years before she even came out. And her talk show has been on almost 2 years. So how is that failing?
It had miserable ratings. She had to pull the "coming out of the closet" stunt to try to save it and it failed. In case you hadn't noticed the networks will bend over backwards to accomodate homosexuals. Nearly every sitcom features a homosexual. The general public didn't think she was funny as evidenced by the ratings.
