Yahoo pits neighborhoods against each other with it’s newest out of home campaign in San Francisco combining social gaming and competition.  These newly installed interactive 72-inch touch screens at bus stops keep commuters busy with four addictive games. The winning neighborhood gets an OK Go concert featured in their neighborhood. This is a great way to get people interacting with the brand- catching them at a perfect time. Very clever. Stay tuned for the winner announced in two months- I’m rooting for my old neck of the woods, pick it up Marina. Via AdFreak.
