Newhart first began his career in comedy in the 1950s. He released his comedy routine on vinyl, "The Button-Down Mind of Bob Newhart," in 1960.

He was later received the Grammy Award for album of the year.

"When I first started out in stand-up, I just remember the sound of laughter," he once said. "It’s one of the great sounds of the world."

He transitioned to television in 1961 with the launch of "The Bob Newhart Show." The half-hour variety show ran for one season before its cancellation, despite being nominated for numerous awards.
