'Brother' biggest on Sunday

''Big Brother'' was easily the top-rated broadcast program in key demos Sunday, lifting CBS to victory over Fox's all-repeat comedies and ABC's ''The Bachelorette'' special. According to preliminary national estimates from Nielsen, ''Big Brother'' averaged a big 2.8 rating/9 share in adults 18-49 and 8.1 million viewers overall in the 8 o'clock hour Sunday, dominating its timeslot and rising 12% week to week. Also for the Eye, ''60 Minutes'' (1.3/5 in 18-49, 8.8 million viewers overall) gained vs. last week as well, while 9 p.m. newcomer ''Same Name'' (1.4/4 in 18-49, 4.4 million viewers overall) was down slightly from its modest bow. A repeat of ''CSI: Miami'' capped the night (1.2/3 in 18-49, 5.2 million viewers overall). Fox ran a close second to CBS on the night among adults 18-49, getting good production from repeats of ''The Simpsons'' (1.6/5 in 18-49, 3.6 million viewers overall), ''The Cleveland Show'' (1.6/5 in 18-49, 3.3 million viewers overall), ''Family Guy'' (2.1/6 in 18-49, 4.2 million viewers overall) and ''American Dad'' (1.8/5 in 18-49, 3.7 million viewers overall). ABC opened with encores of ''America's Funniest Home Videos'' (1.1/4 in 18-49, 4.8 million viewers overall) and ''Extreme Makeover: Home Edition'' (1.1/3 in 18-49, 4.5 million viewers overall) before picking up some from 9 to 11 p.m. with the special ''The Bachelorette: The Men Tell All'' (1.6/4 in 18-49, 5.4 million viewers overall), airing in advance of tonight's season finale. Though it doubled the ratings performance of the repeat dramas that ABC aired in the 9-11 p.m. block last week, ''Men Tell All'' was down sharply from its performance of a year ago, when it aired in the show's regular Monday time period. NBC had another quiet Sunday with ''Dateline'' (0.7/2 in 18-49, 4.3 million viewers overall), a two-hour repeat of ''America's Got Talent'' (0.9/3 in 18-49, 4.0 million viewers overall) and closing things out with firstrun alternative series ''The Marriage Ref'' (0.9/3 in 18-49, 2.9 million viewers overall). Preliminary 18-49 averages for the night: CBS, 1.6/5; Fox, 1.5/5; Univision, 1.4/4; ABC, 1.3/4; NBC, 0.8/2. In total viewers: CBS, 6.6 million; ABC, 5.0 million; NBC, 3.8 million; Univision, 3.5 million; Fox, 3.1 million. Contact Rick Kissell at rick.kissell@variety.com
