Jay's by far the "King of Late Night" and is going out on top. Howard's buddies Kimmel and Letterman can't touch him. Wiggy only wishes he was this popular and successful, he's a jealous little bitch. November 21, 2013 | 03:17PM PT 'Tonight Show' is beating CBS' 'Late Show' by 51% in 18-49 demo this fall; Kimmel boosts ABC Rick Kissell NBC continues to be the most popular latenight choice of Americans, with Jay Leno, whoâ€™s set to exit â€œThe Tonight Showâ€ in just a couple of months, and Jimmy Fallon, the man who will replace him, both off to their best ratings starts in five years. The Peacock latenight hosts have opened up considerable distance on their CBS competition and also had no problem topping ABCâ€™s revamped lineup, which has had â€œJimmy Kimmel Liveâ€ leading into â€œNightlineâ€ since January. Leno saw a boost in his final months the first time he was ready to ankle â€œTonightâ€ in 2009, but it must be encouraging for NBC to see his replacement come on so strong this fall. In fact, Fallon is now outdrawing David Lettermanâ€™s CBS show in young adults even though the latter starts an hour earlier. Looking at the numbers for the first eight weeks of the television season (Sept. 23-Nov. 17), â€œTonightâ€ is the clear leader in the three-network weeknight battle at 11:35. Its average adults 18-49 audience of 1.11 million â€” a three-year high â€” is up 12% from last year at this time and comfortably ahead of â€œJimmy Kimmel Liveâ€ (919,000, up 37% from his year-ago average when it started 25 minutes later); ABCâ€™s lineup is seeing slight overall gains from last year in 18-49, even though â€œNightlineâ€ remains down sharply in its new, later time. CBSâ€™ â€œLate Show With David Lettermanâ€ continues to struggle, with its 18-49 audience (736,000) down 20% from last year. As a result, the â€œTonight Showâ€ advantage over â€œLate Showâ€ has swelled to 51% after standing at just 7% at this time a year ago.
