'America's Next Top Model' to end long run

America's Next Top Model, a reality-TV institution, will end its run when the CW show's 22nd season concludes in December.

The long-running reality competition, hosted by executive producer Tyra Banks, started in 2003 on UPN and was the first series to premiere on the new CW network on Sept. 20, 2006. The show's finale, which will name a top model for the 22nd season, is scheduled for Dec. 4 (9 p.m. ET/PT).

Banks tweeted her thoughts about concluding the show on Wednesday.

TYRA MAIL! Thinking #ANTM22 should be our last cycle. I truly believe it's time. May your pics be forever fierce. Keep on Smizing! Tyra— Tyra Banks (@tyrabanks) October 14, 2015
