So, working in advertising, I am used to seeing rejected commercials. The industry loves to pass around spots that were just too racy for TV, or aired in Europe (mostly) but would never air in North America.
Today's example, however, I just don't get. PornHub (it's exactly what you think it is) produced a spot for the Superbowl that was rejected by CBS. I've included a link below (it's totally SFW). It's the most innocuous commercial I have ever seen. Am I missing something?
