According to a site sponsored by the English Department at the USC at Berkley, "Popular culture has been defined as everything from "common culture," to "folk culture," to "mass culture." While it has been all of these things at various points in history, in Post-War America, popular culture is undeniably associated with commercial culture and all its trappings: movies, television, radio, cyberspace, advertising, toys, nearly any commodity available for purchase, many forms of art, photography, games, and even group "experiences" like collective comet-watching or rave dancing on ecstasy.
Following are several links to sites dedicated to popular culture in America.
