My formative years were especially influenced by MAD Magazine. I started reading in the late 1980's, but I quickly amassed a large collection of back issues and book collections going back to the magazine's start in the 1950's. In fact, my introduction to many cultural icons was through MAD's satire of them before I'd even experienced the original. MAD was full of ingenious political and pop-culture satire but perhaps the primary target was advertising.
MAD even attacked the subtle details of things like the proportions of cereal boxes. Every manipulative detail of the ad-biz was ridiculed and laid bare.
Most substantially, MAD magazine itself had no third-party ads from 1957 through 2001. This practice went against all business assumptions about the publishing industry. They did everything backwards. Cheaper paper, black-and-white, no ads, and they purchased the rights to submitted artwork outright so they could use and reuse it freely. They savagely satirized all of America's consumer culture, ad-biz, and celebrity obsessions. Their interests were aligned solely with the readership.
