Conan O'Brien Conan O'Brien

Conan O'Brien is going to TBS.

"In three months I've gone from network television to Twitter to performing live in theaters, and now I'm headed to basic cable," O'Brien said in a statement. "My plan is working perfectly."

O'Brien also tweeted: "The good news: I will be doing a show on TBS starting in November! The bad news: I'll be playing Rudy on the all new Cosby Show."

Conan O'Brien says goodbye to Tonight Show

NBC dumps Conan in $45 million deal; reinstates Leno as Tonight host

Rupert Murdoch, the head of Fox's parent company News Corp., told The Wall Street Journal in February that Fox TV executives Peter Rice and Kevin Reilly would have to "show us we can do it and be fairly confident of making a profit" for the network to hire O'Brien.

O'Brien, who hosted Late Night for 16 years, started The Tonight Show with Conan O'Brien — his dream job — on June 1. He drew lower numbers than his predecessor, Leno, in part because The Jay Leno Show provided a weaker lead-in than the 10 p.m. programming it replaced.

In January, NBC concocted a plan to move Leno back to 11:35 with a half-hour show, to be followed by O'Brien at 12:05 a.m. O'Brien chose to leave The Tonight Show, saying that walking away was "the hardest thing I have ever had to do."
