On your mark ... get set ... go... viral!

That's the concept behind a new cartoon Brand Tracker from Unruly Media that shows Olympic sponsors racing to collect the most buzz from their online commercials. The more shares advertisers get on Facebook, Twitter and elsewhere on the Internet, the closer they get to the finish line.

Now viewers can see how much social media bang the Olympics official sponsors are getting for their buck. The race will be updated every few days, according to Unruly, which recently began its Social Video Lab, a testing ground for advertisers to estimate how popular their video ads will be.

Procter & Gamble, which AdWeek says received a huge boost from its tear-inducing "Best Job" spot celebrating Olympic moms, led the pack by far with 2.2 million shares as of Wednesday evening. Adidas was in second place with 132,500 shares followed by Samsung with 85,318.

Other famous Olympic advertisers like Coke, Visa and Cadbury have some catching up to do. As of this writing, the three were out of medal contention.

We just hope none of the companies tests positive for steroids.
