In the younger half of the key 18-49 demographic, adults 18-34, Conan won the week by a towering 164 percent margin (930,000 adults 18-34 vs. "Late Show's" 352,000), up from 103 percent for the same week last year and up from 50 percent for "Tonight" this season through the end of May.

The press release also includes some interesting info regarding the average age of late night viewers. During the week of June 15, the median age of Conan's audience was 45.8; Letterman's, 57.0; Jimmy Fallon, 44.0; Craig Ferguson, 53.5; "Nightline," 57.9; and "Jimmy Kimmel Live," 53.1.
