NBC Reveals Conan Exit Date, Jimmy Start Date

Musical hosting chairs begins next month as O'Brien signs off from Late Night

Conan O'Brien will officially be out of work come Feb. 20.

NBC just announced that date as the last O'Brien-hosted Late Night. New overlord Jimmy Fallon will take over the desk beginning March 2.

O'Brien, who has been the Late Night ringleader for 15 years, won't be needing unemployment, though. In NBC's version of musical chairs, he's due to assume Tonight Show duties on June 1, three days after Jay Leno signs off .

Leno will ultimately resurface in the Peacock's prime-time lineup next fall, fronting The Jay Leno Show weeknights at 10 p.m.

Fallon, meanwhile, continues to hone his shtick online at NBC.com.
