Conan O’Brien’s Tonight Show was notorious for performing worse than Jay Leno’s, and when Leno took the show back, he went back to winning the late night wars—or did he? TV By the Numbers has looked at recent ratings and discovered that although Leno started out doing well, his current “ratings trend” is actually a bit below Conan’s in the same period, and he is back to being tied with David Letterman in the 11:30 slot—and this is before O’Brien’s cable talk show starts competing with both of them. And as one observer noted, Leno doesn’t even have Conan’s excuse for these ratings: having Jay Leno as a lead-in.
