YouTube has 55 million unique visitors every month and 40 percent of them use the service on mobile phones. The Google-owned online video sharing venue said that more than a billion people now use YouTube each month.
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 its launch.
Google, which bought YouTube in 2006 for USD 1.65 billion, is yet to disclose whether the service has turned a profit.
YouTube has gradually added professional content, such as full-length television shows and movies to its vast trove of amateur video offerings in a bid to attract advertisers.
