The premiere of ABC's Jimmy Kimmel Live did nothing to harm the
performance of NBC's king of late-night, The Tonight Show with Jay Leno,
which won last week by its largest margin in 21 weeks.
Original episodes of Leno, from 11:35 p.m. to 12:35 a.m., scored a 2.2
rating/10 share in adults 18 through 49 against repeats of The Late Showwith David Letterman that averaged a 1.4/6 in the demo, according to
Nielsen Media Research.
At ABC, the pairing of Nightline at 11:30 am with the first half of
Kimmel from 12:05 a.m. to 12:35 a.m. averaged a 1.3/5 in the demo, with
Kimmel's ratings dropping to a 0.8/4 from Nightline's 1.3/5.
Still, ABC was pleased with Kimmel's performance against CBS'
TheLate Late Show with Craig Kilborn. In the second half of
Kimmel and the first half of Kilborn, the two shows tied in
adults-18-through-49 rating, with Kimmel prevailing in adults 18 through
34 with a 0.8, 33 percent higher than Kilborn's 0.6.
NBC's Late Night with Conan O'Brien also dominated its time period --
12:35 a.m. to 1:35 a.m. -- winning adults 18 through 49 with a 1.1/7. That
defeated Kilborn in the same time slot, which scored a 0.7/5 in the demo,
and the second half of Kimmel, which averaged a 0.8.
