David Letterman might be late-night TV’s one constant this year, according to a Broadcasting & Cable report that says he is discussing a new deal to keep the Late Show on CBS beyond 2010. With NBC shifting Conan O’Brien over to The Tonight Show later this year, handing Jimmy Fallon O’Brien’s spot on Late Night, and giving Jay Leno a new prime-time show, CBS might be opting to hold steady with Letterman at 11:30 p.m. leading into the increasingly popular Craig Ferguson at 12:30. Letterman, who is believed to make more than $30 million per year, is currently working under the terms of a four-year deal that has him on through August 2010.
