LinkedIn: 100 Million Members and Counting

Launched in 2003, LinkedIn now boasts 100 million users, as of today. The professional social network is used in over 200 countries. 44 million members reside in the United Sates, while another 56 million hail from around the rest of the world, with Mexico and Brazil seeing the largest growth rates. Some statistics: there are over 1.3 billion connections between LinkedIn’s members and nearly 80 million job transitions/changes tracked on the network.

However, there’s a catch: the company’s active users are less than its registered users. From the company’s S-1 filing: “…a substantial majority of our page views are generated by a minority of our members? If the number of our actual members does not meet our expectations or we are unable to increase the breadth and frequency of our visiting members, then our business may not grow as fast as we expect, which will harm our operating and financial results and may cause our stock price to decline.”

To draw a comparison, Facebook has 600 million users.
