Via Business Insider:
Facebook has as many users today as the whole internet had in 2004, the year Facebook was founded.
The data comes from Royal Pingdom, which cites an internet growth statistics site that plots the amount of users using the internet in any given year.
Facebook has over 800 million active users today, while seven years ago in May 2004, there were only 757 million people using the internet worldwide in grand total.
In other eye-popping numbers: it’s now estimated that over 500 million people are now online in China and it’s estimated there’ll be 4.5 billion global mobile phone subscribers by 2012.
