The summer television season has seen one show dominate the viewership numbers this year, with a sizable gap between it and everything else on TV. The show is NBC’s “America’s Got Talent.”

The AP reports: “The NBC talent show, this summer augmented by the addition of Simon Cowell as a judge, was seen by 12.8 million people on [Tuesday], the Nielsen company said. That’s more than 4 million viewers more than any other program on the air last week.”

Additionally, a Wednesday night broadcast of “America’s Got Talent” highlights placed third for the week with 8.48 million viewers, according to Nielsen. The No. 2 show of the week of July 4-10 was also an NBC telecast, with Sunday’s “Olympic Trials” delivering 8.58 million viewers.

Meanwhile, Fox isn’t faring nearly as well. “A week after Fox hit a new low for one of the top four networks with a weekly viewership average of 1.96 million, it slipped to 1.94 million last week,” the AP reports. “Only one of its programs finished among Nielsen’s top 50.”

Nielsen data for the week shows ABC’s “Celebrity Family Feud” came in as the highest-ranked non-NBC program, fourth overall with 7.43 million viewers, while CBS’s “60 Minutes” rounded out the top five with 7.35 million.

The report notes that the week of July 4 is traditionally one of the least-watched TV weeks of the year.
