Mad's covers collectively provide a satirical history of America, and one you can easily browse at Doug Gilford's Mad Cover Site, "a resource for collectors and fans of the world's most important (ecch!) humor publication." Gilford started the site back in 1997, a year that saw Mad's covers take on such phenomena as The X-Files, the Spice Girls, the Tamagotchi, and Seinfeld.
