After the fake Justin Bieber ad we saw earlier this week, here's a real one from Google Chrome, which uses everyone's (least) favorite teen sensation to illustrate how the Web browser allows people to communicate with each other and maybe rise to international superstardom. The effectiveness of the ad depends on how you feel about Bieber, I think. But his success is certainly a story about the Internet, so it's hard to argue with that. Luckily, though, Chrome also made one with Lady Gaga, who doesn't inspire quite so much hate from the public.
