Fox and Paramount Pictures
Eleven may be a magic number for sitcoms. American television stalwarts "MASH" and "Cheers" each featured a cast of 11 main characters, and both shows ran for 11 seasons. "MASH" followed a team of doctors of a Mobile Army Surgical Hospital stationed in South Korea. "Cheers" chronicled the lives of the workers and regulars at the Boston bar Cheers. Other shows that capped at 11 seasons include "Frasier," "The Jeffersons" and "The Carol Burnett Show."
