At the TechCrunch DISRUPT conference in New York last month, Facebook's advertising chief Carolyn Everson revealed that brands are receiving 50 million "likes" on Facebook every single day. And the truly astonishing figure is this: Those 50 million likes represent just 5 percent of the more than 1 billion "likes" per day that Facebook has been generating since the "like" plugin for Web pages rolled out one year ago. In other words, 50 million “likes” a day is just a starting point, with an enormous amount of room for growth.
