Best know to me for the "war on the worlds" prank broadcast where they did a radio show to HG Wells' famous story.
The panic is caused was created out of whole cloth by the newspapers to show everyone how dangerous the new media of radio can be. Anyone on the Internet should get a twinge of recognition. Technology changes, but Yellow Journalism never does.
And as we all know, Orson took it lying down.
And the dude made history and there's lots of awesome but I still love these outtakes.
