Dont’t expect Jon Stewart to be back as host of the Oscars. The audience tuned out of the deadly dull Oscarcast in droves, resulting in the worst ratings in history, a 20 percent drop from last year, when Ellen DeGeneres hosted. With an estimated 32 million viewers, the smug Stewart beat the record he previously set for the least-watched Oscarcast, back in 2003. Of course, the little-seen Best nominees didn’t help, nor did a show that was slapped together in a week after the end of the writers’ strike. But there was no writers strike back in 2003, when the show managed just a million more viewers.
