Academy of Country Music Awards Pulls In Most Viewers Since 1998

Taylor Swift, Miranda Lambert and other stars give CBS a big night

The 50th Academy of Country Music Awards on CBS last night was the most-watched since 1998.

The super-sized special, which aired from 8-11:30 p.m., was watched by 15.77 million viewers, up 10 percent from the 2014 ACMs and making it the No. 1 show of the night on broadcast TV. In the younger demos, the awards drew a 3.6 rating and 11 share among adults 18-49 (up 6 percent from 2014) and a 2.6 rating and 9 share among adults 18-34 (up 4 percent).

This was the fist year the ACMs extended to 11:30 p.m. Compared to last year's 8-11 p.m. broadcast, this year's show had 13 percent more total viewers. CBS' ratings beat NBC's, ABC's and FOX's combined.

Not only did the show put up big TV ratings, but it also set a Guinness World Record for most attended live awards show of all-time. The ACMs were held at the 80,000-seat AT&T Stadium in Arlington, Texas.

The ACMs were also the No. 1 social broadcast of the day, according to Nielsen Social data.
