Hugh Downs was a radio and TV broadcaster into the late 1990s. He was Jack Paar's sidekick on the "Tonight Show," co-host on the "Today Show" and anchor on "20/20." Hugh was also the announcer on the "Kuka, Fran and Ollie Show," "Sid Caesar Hour" and the game show "Concentration." Downs was very much involved in public service, including consultant to the United Nations refugee programs and on the board of the U.S. Committee for UNICEF. On his last 20/20 appearance, he was one of the first public figures to say that marijuana should be legalized.
