Financial Times: Like most of the biggest media websites, BuzzFeed reaches the majority of its audience over a mobile device. The company says that more than 70 percent of its content is viewed on mobiles, with more than 200 million monthly unique users visiting its website. The growth of smartphones has made BuzzFeed “prime time,” according to CEO Jonah Peretti. “Our prime time is the same as prime time television in the evenings and the majority is happening on mobile.”
