The network's cutting ties with "Tonight Show" host Conan O'Brien after he declined to push his show back a half hour to make room for Jay Leno's return to late night.
A couple of controversy-filled weeks conclude tonight, when O'Brien says farewell.
O'Brien and NBC have agreed to a $45 million deal that includes severance for his staff. Jay Leno returns to the show in March.
O'Brien's very first tonight show guests, Will Ferrell, will be part of the final show, along with Tom Hanks.
