The Kennedy Center Honors will mark 40 years on CBS. The network has signed a new agreement with the John F. Kennedy Center for the Performing Arts that will keep the annual Kennedy Center Honors on CBS through 2018. The special has been broadcast on CBS each year since its debut in 1978. “The Kennedy Center Honors continues to be one of the most prestigious broadcasts on all of television, and we are honored to be its host,” said CBS Corp. president and CEO Leslie Moonves. “It is a unique event that reinforces our country’s collective appreciation for the performing arts with tremendous class, style and, yes, entertainment.” The Kennedy Center Honorees are recognized for their lifetime contributions to American culture through the performing arts — dance, music, theater, opera, motion pictures or television. Last year, the Kennedy Center Honors won an Emmy Award for Outstanding Variety, Musical or Comedy Special for the third consecutive year. George Stevens Jr., co-created the Kennedy Center Honors in 1978 with Nick Vanoff, and has produced and co-written the show for 34 years. Michael Stevens has produced and co-written the show for the past five years.
