NBC executives must have been thinking, If only we could do as well during the regular season as we do during the summer after America's Got Talent clobbered the competition on Tuesday as it averaged 9.49 million viewers, peaking in the 10:00 p.m. and 10:30 p.m. half-hours with 10.19 million. Over at ABC, Extreme Weight Loss wound up with extreme ratings losses as it averaged just 3.33 million viewers. And Fox's once-powerful So You Think You Can Dance managed to attract just 4.36 million viewers.
