Along with the fun of watching the ball drop in Times Square, there is also the sobering reality of terrorism fears, which have resulted in a significant spike in security. New York deployed 6,000 police officers to Times Square for the festivities.
"[Security] is very tight," Ryan Seacrest told Good Morning America. "They do such a great job. We will be very safe tonight."
The expected one million revelers will be watched over by officers equipped with long guns, radiation detectors and bomb-sniffing dogs.
Performers for the annual show include Nick Jonas, 5 Seconds of Summer, One Direction, Demi Lovato, Luke Bryan, Carrie Underwood, Wiz Khalifa and Taylor Swift, who will drop her "Out of the Woods" video during the telecast.
Dick Clark's 2016 New Year's Rockin' Eve With Ryan Seacrest starts at 8 p.m. on ABC.
