In a virtual repeat of last year, Kenny Chesney and Carrie Underwood received the same awards they did last year during CBS's telecast of the Country Music Association Awards -- entertainer of the year and female vocalist of the year, respectively. Likewise the telecast drew about the same ratings -- an 8.9 rating and 14 share versus last year's 9.0/13. Wednesday night's network lineup also saw the apparent collapse of Bionic Woman on NBC, which fell to a fourth-place 4.4/7 in the 9:00 p.m. hour, representing half the number of viewers it attracted when it debuted on Sept. 26.
