How Many Products Have Been "Liked" on Facebook?

With more than 900 million users and the potential for more, Facebook FB towers over the competition as the leader in social media. But have these users resulted in a significant number of "Likes" for products that are promoted on the site? According to AllThingsD, Facebook users have "Liked" 5.6 million products. The publication does not state whether or not these are individual products, or if it counts multiple "Likes" for the same product. Either way, the number is still impressive. AllThingsD also reports that more than 70 percent of e-commerce sites have added the Facebook "Like" button to their pages. Follow me @LouisBedigianBZ
