Engagement: Super Bowl Ads Going Viral

"Welcome to the Viral Video Chart, Super Bowl edition. The week after the big game, all ten slots were taken over by spots that aired during the Super Bowl, racking up 44.7 million combined views and shoving aside some durable online campaigns like Evian's "Roller Skating Babies," Microsoft's Xbox Project Natal and DC Shoes' "Gymkhana Two."
...

"According to Visible Measures, about 20% of all views of Super Bowl spots (18 million) were socially driven, meaning viewers distributing the video on their own through Facebook, blogs and links passed around via Twitter.

Increasingly, advertisers aren't just trying to impress an audience, they need them to participate, too."
