Because I was just assaulted with a page that looked like this. And oh yeah, that Wal-Mart ad? It’s a video, with no stop/pause button. And those two little ads? They move around randomly on the screen so you can’t close them.

The Consumerist gives a great rundown of some pretty shocking ads from history, including an ad for asbestos that talks about evacuating the World Trade Center (well before 9/11) and a Bayer Heroin ad!
