Facebook has got more than 300 Million users, with 50% of them logging on each day, a worldwide total of 6 Billion minutes is spent on facebook each day by its users with 40 million status updates each day available in over 70 languages. Which in comparison to its nearest competitor, Bebo, which has got only 40 million user accounts.

facebook itself does not actualy sell physical products as it gets most of its revenue from occasional adverts and other sources such as game add ons, there are no actual adverts untill a user makes an account and loggs in, which some may arrive at the side of the screen or the top depending on what the user is doing, facebook will then get paid if the user clicks on any of these things. The next thing is that there are many games available to play on facebook, some of which require physical money to buy add ons for use within the game, which facebook will then get revenue from these. There are also sponsored groups within facebook that companies will pay money for.
Facebook has got one of the strongest mobile support systems from any company, with over 65 million users using the mobile service, this is greatly helped by devices such as the iphone and googles android operating system as these have dedicated applications for facebook, and it found that users that use facebook on their mobile phones are over 50% more active than users that dont. I think this is a market that will continue to grow over time as more and more people start to use the service on their mobile devices, with facebook possably needing to make more of the desktop sites features available to the mobile users.
