The Price Is Right is the longest-running game show on US television and is viewed by international audiences every weekday.

From the first series in 1972 to 2007, Barker was its cheerful face. During his six-decade radio and television career, he received 19 Emmy nominations.

According to his agency, he died of natural causes at his residence near Los Angeles.

“The World’s Greatest MC [Master of Ceremonies] who ever lived, Bob Barker, has left us,” publicist Roger Neal announced on Saturday.

Barker was born in December 1923 in Washington State and served in the United States Navy during WWII before embarking on a career in radio and, subsequently, television.

Excited participants on CBS’s The Price Is Right were famously encouraged to “come on down” before Barker evaluated their knowledge of the prices of consumer products in exchange for prizes.

Drew Carey, a comedian, took over as host in 2007.

When Baker died, Carey tweeted, “There hasn’t been a day on set that I haven’t thought of Bob Barker and thanked him.” I will cherish his memory for the rest of my life.”
