TV Ratings: CBS Sweeps Sunday With 'Big Brother'
Sunday night belonged to CBS. With mostly encore competition, the network easily won in both adults 18-49 and total viewers.
Big Brother continued its strong and steady run this summer, topping the night with a 2.1 rating in the key demo. Unforgettable (1.0 adults) and Reckless (0.6 adults) were also even.
ABC was CBS' only real broadcast rival with originals, though it fell short in all hours but 10 p.m. Wipeout (0.8 adults) dropped three-tenths of a point before a steady Rising Star (0.9 adults).
