The first (and best) US television newsmagazine, founded by CBS News' Don Hewitt in 1968 (he continues to run the ship). As full-length documentaries were becoming less and less a factor on prime-time TV, this format became the best compromise - three extended-length news stories in one hour. They invented the "ambush interview", in which Mike Wallace and crew would show up to ask a question or two to some miscreant. Always call your lawyer before talking.
