I think Channel 11 made a mistake in taking off "Entertainment Tonight" at 8 p.m. and starting another news program instead. Who needs it? For those who can't afford the Hollywood trade paper Daily Variety and who go to sleep before Carson, the combination of "E.T.," "PM Magazine" and "Merv Griffin" was a winner. Too bad KTTV management didn't think so.
