HOLLYWOOD, CA (DPI) - Remember Marilyn Manson, Green Day, The X Files and cellular phones? FOX TV Executive Jeff Kamen is betting that you do. Kamen, 22, is the brainchild behind FOX's newest retro-sitcom, That '90s Show. "The thing with Retro is that, honestly, that stuff is way too old," Kamen told reporters at a Beverly Hills press conference. "I mean, the '70s? Who remembers the '70s? Most people weren't even alive then. Same with the '80s. What's so funny about stuff that happened when I was in diapers?"
