From TVNewsday:

Jay Leno's last show will be Friday, May 29, and Conan O'Brien will start the following Monday, June 1, NBC executives told a Television Critics Association meeting Monday.

And our sources tell us that O'Brien will be moving to LA early next year.

Since it was also announced that Late Night will
be in reruns starting sometime "in the first quarter."

Okay, Conan - just stay away from neighborhoods with 'Heights' in the name. That's not a tall joke. That's a fact of life in LA.
