February sweeps ratings are in for the early-morning and late-night network TV shows, and each of the networks had something to boast about. ABC could trumpet the news that its Good Morning America won a clear victory over NBC's Today show among total adults and adults in the 25-54 age group. For the month it averaged 5.67 million viewers versus 4.82 million for Today. CBS This Morning wound up with 3.01 million (a 15-percent rise from a year ago, the greatest improvement of any of the morning shows). NBC's The Tonight Show with Jay Leno remained the most-watched late-night show, averaging 3.5 million viewers. But CBS's Late Show with David Letterman was hot on its heels with 3.3 million viewers. ABC's Jimmy Kimmel Live posted an average of 2.5 million viewers. Among the 18-49 demo, the late-night race was tight, with Leno drawing 1.02 million viewers, Letterman 941,000 and Kimmel 913,000. The race was equally as tight in the late-late-night period, with NBC's Late Night with 1.7 million viewers edging out CBS's Late, Late Show and ABC's Nightline with 1.6 million each.
