Bob Barker, known for hosting the game shows The Price is Right and Truth or Consequences, has passed away.

Per The Hollywood Reporter, after a decade on the radio, Barker was named host of the nationally televised Truth or Consequences in December 1956 and stayed with that program through 1975.

In his career, Barker garnered 15 Emmy awards. He was presented a Daytime Emmy Lifetime Achievement Award in 1999 and was inducted into the Academy of Television Arts & Sciences Hall of Fame five years later.

Barker generated buzz when he refused to dye his hair in 1987 due to the animal products used in hair dyes, The same year, he declined to go on as host of the Miss USA and Miss Universe pageants after learning about the contestants wearing animals skins.

You may know his animal activism more from his famous closing line on each episode of The Price is Right, which he hosted from 1972 to 2007, "have your pets spayed or neutered."

Barker trained as a Navy fighter pilot during World War II, though he did not serve on active duty. He found his true calling as a host when during his tenure at a radio station, one staffer failed to show up at the last minute and he did his first audience-participation show. It was an instant spark.

At 32 years old, Barker got an audition for Truth or Consequences. The show went on to become the No. 1 show on daytime television and then went on five times a week in syndication.

In 1998, upon the taping of the 5,000th episode of The Price Is Right, CBS dedicated Stage 33 at CBS Television City as the Bob Barker Studio.

Barker had a good sense of humor and could poke fun at himself, and found a brand new generation of fans when he appeared on the Adam Sandler movie Happy Gilmore, playing himself — and beating up Adam Sandler during a celebrity golf tournament. (At one point, Sandler yells "The price is wrong!" after slugging Barker... which Barker more than returns.) “Nobody had heard of Adam Sandler until I beat him up,” Barker teased. He and Sandler won the 1996 MTV Award for best fight.

Though Barker is known for his game show roles and activism, he did appear on a handful of other TV shows, including Futurama, How I Met Your Mother, and Bonanza where he guest-starred in 1960.

Barker was 99 when he passed.
