So now that Facebook has reached 500 million members, the big question is where Facebook will get the necessary users to reach its next important milestone, one billion, one which will make Facebook, if it was a country, the third biggest in the world and certainly the richest one.
The world's biggest social networking website is already looking forward to expand in territories where it still accounts for a minority of the users online, continents like Africa or Asia where Facebook only accounts for one or two percent of the total population.
According to O'Reilly Research, the share of active Facebook users coming from Asia for example is growing fast, while North America and Europe have dropped showing that the momentum is with the less mature markets.
Facebook is also likely to get more traction from the 40+ audience, one which is currently overwhelmingly under represented across all territories but which bears some impressive promises. Figures show that the older portions of the audience account for some of the strongest growth figures across all nine territories.
Right until now, Facebook has been an ace at getting more eyeballs and the next step, like for Twitter, is to monetize these fabulously high members numbers; guesstimates put the revenue of the entity at around $1 billion per annum, that's roughly $2 per user.
