Perez Hilton reports The Late Show with David Letterman has beaten The Tonight Show in ratings for four consecutive weeks. This is the first time in a decade that Letterman has stayed above the competition for so long.

Letterman has been hosting the show since 1993, while Conan O’Brien, the new host of The Tonight Show, only just took over for Jay Leno in June.

The Late Late Show with Craig Ferguson, which follows Letterman on CBS, has scored higher ratings than NBC’s Late Night with Jimmy Fallon for three weeks running.
