Advertising as something other than advertising (a non-exhaustive list): historic 1950s-era advertisement for Shasta Cola, AdCritic to charge for looking at TV ads, movie trailers as entertainment, vintage television commercials collected for entertainment and historic purposes, the Smithsonian has a set of Burma Shave signs. With apologies to Arthur Clarke, perhaps the sign of any sufficiently advanced society is its ability to make advertising indistinguishable from traditionally-accepted forms of creative output.
