Location: Palo Alto, Calif.
CEO: Mark Zuckerberg
Revenues: $100 million (est.)
What they do: Social networking
What makes them disruptive: Facebook offers an addictive blend of silliness and serious tools to stay up on what your friends and contacts are doing. It trumps other efforts with its functionality and ease of use.
The tech that makes them tick: Its REST-based open platform supports a robust ecosystem of third-party developers creating sticky, if occasionally annoying applications that continue to strengthen Facebook?s grip on its user base.
Who they are disrupting: The main losers are e-mail, the local bar and Saturday night. If it isn?t on your Facebook, it didn?t happen.
