SAN FRANCISCO (AFP)More than a billion people use YouTube each month, with viewing on smartphones helping drive growth, the Google-owned online video sharing venue said. In a blog post, the YouTube team noted that nearly one out of every two people on the Internet visits the website, which has grown into a global hit since launching in 2005. “If YouTube were a country, we’d be the third largest in the world after China and India,” the team said. “PSY and Madonna would have to repeat their Madison Square Garden performance in front of a packed house 200,000 more times. That’s a lot of Gangnam Style,” it added referring to the South Korean rapper and American pop singer.
