March 20 Google Inc's YouTube said on
Wednesday the number of unique users visiting the video-sharing
website every month has reached 1 billion, about six months
after social media company Facebook Inc also said it had
the same amount of users.
"Nearly one out of every two people on the Internet visits
YouTube," the video website said in a blog post. ()
Facebook said it had passed the one billion user mark in
September, a level of global penetration that has made its
quest for sustained growth more challenging.
