Comedienne Joan Rivers has died.

Rivers first rose to fame in a 1965 guest appearance on Johnny Carson’s Tonight Show, later going on to be a guest host of the NBC franchise. She guested on such 1970s classics as The Carol Burnett Show and The Hollywood Squares (see a 1970 appearance below). In 1986, she hosted a short-lived late night competitor (The Late Show Starring Joan Rivers) on the fledgling Fox network.

Joan Rivers passed away today in New York. She was 81 years old.
