The Retroist is a veritable treasure trove of 80's (and 70's) goodness. TV commercials, catalogs, and of course the poetry of Mr. Leonard Nimoy. The Youtube channel alone is worth the price of admission-- Tobor! Diet Rite! Candyland!
Retrostatic is a treasure trove of 80's (and 90's) TV commercials--from PSAs of singing pills to the Post cereal Create-A-Villain contest (and so much more). Also, cartoons, with descriptions and opening sequences of everything from Alf Tales to Thundercats.
