conan lettermanCBS boasted today that rebroadcasts of the Late Show with David Letterman delivered a larger audience than first-run broadcasts of The Tonight Show with Conan O’Brien, according to Nielsen live plus same day ratings for the week ending August 7th. Dave delivered a 2.1/06 in households with an average of 2.95M viewers, beating first-run Conan shows in households (vs. 2.0/05, +5%) and viewers (vs. 2.94M). This marks Letterman’s 5th consecutive weekly win in viewers over O’Brien.

CBS also said The Late Late Show with Craig Ferguson topped Late Night with Jimmy Fallon for the 4th consecutive week. Ferguson posted a 1.1/04 in households with 1.41M viewers, beating Fallon in households (vs. 1.0/04, +10%) and viewers (vs. 1.39m, +1%).

Yet NBC’s dueling press release wasn’t more subdued this week, considering. It noted that Conan topped the late night week of August 3rd-7th in 18-49 demos “over all cable and broadcast competition” and that O’Brien’s won the week over broadcast competition in every key demo: adults, men and women, 18-34, 18-49 and 25-54. It said Conan posted week-to-week gains of 8% in 18-49 viewers and 12% in total viewers. But the network downplayed the fact that Letterman was in repeats.

NBC also boasted that Late Night with Jimmy Fallon “out-delivered” CBS’s Late Late Show with Craig Ferguson and ABC’s Jimmy Kimmel Live in adults 18-49, adults 18-34 and other key demos.
