The charismatic former host of one of the most popular U.S. television game shows in history, Bob Barker of "The Price Is Right," has died, his publicist confirmed Saturday. He was 99.

For 35 years, audiences in the United States and in many countries around the world watched every weekday as the famously affable Barker called on excited contestants to "come on down" and test their knowledge of how much consumer goods cost, in return for cash and prizes.

"It is with profound sadness that we announce that the World's Greatest MC who ever lived, Bob Barker, has left us," his publicist Roger Neal said in a statement.
