One of the longest-running broadcast reality series, the CW's America's Next Top Model, is coming to an end, with the current 22nd season as its last as the network has opted not to pick up a 23rd cycle. The series finale will air Friday, December 4.

America's Next Top Model premiered May 20, 2003 on UPN, and was the first series to debut on The CW on Sept 20, 2006. The network is in discussions about a retrospective special to air in late 2016.

"America's Next Top Model was a successful franchise for two networks, first at UPN and then The CW, and it became not just a ratings hit, but a global pop culture phenomenon," said Mark Pedowitz, President, The CW. "I want to thank Tyra and Ken for all their years of success in establishing a show that was not just popular in the U.S., but all across the world."

Top Model has been the most successful reality series on the CW and the longest-running series currently on the network. The show, produced by Tyra Banks and Ken Mok, has come down from its ratings heyday but still does decent business when delayed viewing is factored in. For premiere week, Top Model posted the biggest Live+7 percentage lift of any program, +100%, doubling its Live+same day number to rise to a 0.8 rating in adults 18-49. Additionally, Top Model launched a very successful format that has been produced in over 30 countries.

In a lengthy Instagram post, Banks discussed the decision to end the show.

"I truly believe it's time," she wrote. "Our diehard fans know we've expanded the definition of beauty, presented what Flawsome is, tooched and booched and boom boom boomed, shown the world how to show their neck, rocked couture/catalogue/commercial poses, have found our (and your) light, strutted countless runways, gone on tons of go-sees, added guys to the girls mix, and have traveled around the globe and back again. Yeah, it's time. It really is."
