30% of All Online Traffic Is Porn

Think pornography is popular online? One tech site estimates that 30% of all Internet traffic involves porn, with the world's biggest porno site trumping traffic on CNN or ESPN three times over, the New York Daily News reports. That site, Xvideos, draws 4.4 billion page views monthly—which means enormous traffic when you consider that viewers on porn sites stay an average of 15 to 20 minutes. And that porn sites offer video requiring massive bandwidth.

Take YouPorn, the Web's second-biggest porn site with more than 100 million page views daily. It claims to transfer 100 gigabytes per second. Consider that the entire Internet only moves an exabyte of data daily—and that there are dozens of YouPorn-sized websites—and you get ExtremeTech's 30% estimate, which it considers conservative. "The Internet really is for porn," it quips. (More pornography stories.)
