NBC’s new primetime lineup apparently wasn’t working as well as the network originally thought it would. Jeff Zucker has been receiving less than positive remarks from his critics about how he killed comedy beginning with Thursday night’s “Must See TV” block. Shows such as “Seinfeld” and “Friends” are no longer being produced anymore and the current state of the television sitcom has been anything but favorable. He’s also being blamed for not being able to create any dramas to replace ended series such as “E.R.” or “West Wing”, and now the current state of programming with “The Jay Leno Show” appearing at the 10:00 hour when people are used to a drama being there and Jay’s “Tonight Show” successor, Conan O’Brien, who has unsuccessfully appealed to his audience.

One of the main reasons Conan’s ratings have been higher last week is because of the jabs he has taken against NBC and Leno. “Saturday Night Live” even had its fun with the Leno and O’Brien debacle on their January 16th broadcast.

It’s currently being speculated that O’Brien is out as he has already stated he will not be doing a later “Tonight Show” at 12:05 after Jay Leno’s short half-hour show. It will be interesting to see what happens with this feud between now and February 15th, when the Winter Olympics start airing.
