Infographic: Olympic Sponsors Race for Viral Advertising Gold

Procter & Gamble is the Usain Bolt of 2012 Olympic sponsors, judging by the fun animated infographic below, which pits brands against one another in a mad dash to viral advertising glory.

The chart, from Unruly Media, tracks online ads from official Olympic sponsors, and illustrates—through animated running avatars—which brands are generating the most social-media buzz. The more shares a sponsor's videos earn across Facebook, Twitter and the blogosphere, the faster its avatar runs toward the finish line.

The data in the infographic will be updated twice a day through the London Games. Unruly is also tracking the most-shared individual spots on a special Olympics Ads Chart.

As it stands, P&G, buoyed by its enormously successful "Best Job" spot from Wieden + Kennedy, has opened a sizable lead in the race. Adidas is currently second, followed by BMW. The Brand Tracker infographic is the first piece of research from Unruly's Social Video Lab, which launched last month.
