Forbes has published an article outlining five things every marketer can learn from Audi and Mercedes online video campaigns.

Working with social video analytics company Unruly, Forbes pulled together the most shared videos from the hotly contested automotive market and found that Mercedes Chicken/Magic Body Control and Audi’s Zachary Quinto vs. Leonard Nimoy ‘The Challenge’ gained the top two spots.

As Forbes piece points out, the Mercedes video looks like it was produced on a shoestring budget, while the Audi video looks very expensive indeed. However both had enormous success, with the Audi video having an initially higher viral spike.
