Leno scored a 5.7 rating, compared to 3.0 for Letterman, 3.4 for Nightline, and 1.8 for Kimmel, Entertainment Weekly reports. Jimmy Fallon rode Leno's coattails, beating Craig Ferguson by a 40% margin. The ratings were expected, given the hoopla surrounding Jay’s return. Conan O'Brien’s Tonight Show debut drew huge ratings, too, as did Leno’s early 10pm outings.
