The word from inside ABC is that Jimmy Kimmel Live! should be renamed Begging For Guests. A friend predicts they will dump the "live" aspect, partly because it makes the network nervous and partially because taping earlier may make it a bit easier to get stars to come in and sit on the couch.
Some time in the eighties, Mr. Carson announced that he would start doing The Tonight Show live every evening. He never did. Too many of the guests they wanted were available in the late afternoon but busy in the evening, either with premieres or local performances. Network worries about the "live" part of Mr. Kimmel's show seem to be less about censorship than they are about the show just looking sloppy, tech screw-ups, etc.
