Before founding BuzzFeed, Jonah Peretti helped launch the Huffington Post. In part three of our “Media Beat” interview, the founder shares his experiences using social media to boost traffic.

“What we’ve seen is that with the rise of Facebook, Twitter, StumbleUpon, Reddit and other social platforms, you can actually build a real business,” Peretti said.
