UPDATED: CBS’ Big Brother (2.5/8) towered over the competition last night, up 9% from last week, and led CBS to a nighty victory among the English-language networks in both 18-49 (1.7/6) and total viewers (6.2 million), despite featuring only one hour of original programming, flanked by repeats. ABC (1.5/5, 5.5 million), which had an all-original lineup, was second. The network’s Wipeout (1.8/7) was even with last week, Expedition: Impossible (1.3/4) was down 7% to a series low and Rookie Blue (1.2/4) was down 14% for a season low. NBC’s Love Bites (0.7/2) made a quiet exit. Its final episode was even with last week’s to tie its series low. But in 18-49, the night was won by Univision (1.8/6), which squeaked past CBS with a 3-hour Premios Juventud special.
