NBC victorious in four-way reality rumble

August 09, 2007 Reality had a four-way rumble in Tuesday's primetime, with a rare night of all four networks having original reality shows vying in the 8 p.m. hour. CBS came close with the premiere of "Power of 10," which didn't set any records ablaze though it seemed to give NBC's "America's Got Talent" a run for its money between 8 p.m. and 9 p.m. But "America's Got Talent" (10.7 million, 3.2 rating/10 share in adults 18-49) still came out on top for the 8 p.m. hour and the entire night, according to preliminary estimates released Wednesday by Nielsen Media Research.
