YouTube has announced more than one billion people are now visiting its online video site each month.
The milestone marks another step in YouTube’s evolution from a quirky start-up launched in 2005 to one of the most influential forces in today’s media landscape.
YouTube crossed the one billion threshold five months after Facebook said its online social network had reached that figure.
The vast audience has given YouTube’s owner, Google Inc, another lucrative channel for selling online adverts beyond its dominant internet search engine.
Google bought YouTube for $1.76bn in 2006 when the video site had an estimated 50 million users worldwide.
