Given how NBC's summer is going, the network might want to make sure that everyone it puts on the air in prime time has a good singing voice.
The nation's five most-watched television programs last week were all on NBC, and all were versions of "America's Got Talent" or "The Voice." The Nielsen Co. says that made NBC's the week's most popular network.
Meanwhile, Univision's telecast of the Copa Oro soccer tournament game between the United States and Mexico had nearly 8 million viewers. That's more than anything on ABC or Fox last week.
Nielsen is checking to see whether this is the first time a Spanish-language broadcast made the company's top 10 list.
