The Tonight Show Starring Johnny Carson (1965)
Joan Rivers had already made her Tonight Show debut back when Jack Paar was hosting, but she didn’t get her real breakthrough until Johnny Carson invited her on the show and proclaimed that she was destined to be ”a star.” ”The next day, my life changed,” Rivers once said. She’d soon become a regular on The Tonight Show, later serving as Carson’s permanent replacement.
