MAD Magazine was one of a kind. It was known for its unique brand of satire on all aspects of popular culture and wielded great influence for several decades. Its publisher William M Gaines refused to accept any form of advertising in the magazine and resorted to spoofing popular ads of the day.

They were particularly severe on Big Tobacco. The magazine has a blog and an iPad version now but the magic of the vintage issues can perhaps never come back.
