Before the creation of Facebook
Mark Zuckerberg is a computer programming genius, and was able to hack into the Harvard network just to create a website for fun. Mark created Facemash, a website that allowed people to rate the "hotness" of undergraduate girls at Harvard. Facemash became so popular that in under 2 hours, the site had already logged 22,000 votes. Eventually, the Harvard network crashed due to the influx of usage on the network.
This stunt gained attention in the Harvard newspaper, The Crimson, where Zuckerberg gained the reputation of a computer genius. 
Tyler and Cameron Winklevoss and Divya Narendra had an idea for a social networking site called “Harvard Connection.” The central idea was simple: Put Harvard’s social life online, so guys could meet up with girls without all of the inefficient, time wasting wandering around campus that real life usually necessitated. They had the idea, and they knew Zuckerberg had the computer programming skills to make this idea a reality.

Divya Narendra sent Mark an e-mail expressing interest in using Mark as their computer programmer for Harvard Connection. Mark's initial reaction was "it might be interesting."

The Harvard Connection crew officially thought Mark was on their team however, after 52 e-mails, half a dozen calls and no progress, it appeared Mark was not being responsive and would most likely not be working for them. Instead,  Mark went to his best friend, Eduardo Saverin with an idea for a website where "people put their own pictures up-and not just pictures, but also profiles. where they'd grown up, how old they were, what they were interested in. Maybe the classes they were taking. what they were looking for online- friendship, love interests, whatever."

 The book claims that Zuckerberg stole the initial idea of a social networking site throughout a college network when he created Facebook.
