Zuckerberg began using computers and writing software in middle school. His father taught him Atari BASIC Programming in the 1990s, and later hired software developer David Newman to tutor him privately. Newman calls him a "prodigy", adding that it was "tough to stay ahead of him". Zuckerberg took a graduate course in the subject at Mercy College near his home while still in high school. He enjoyed developing computer programs, especially communication tools and games. In one program, since his father's dental practice was operated from their home, he built a software program he called "ZuckNet" that allowed all the computers between the house and dental office to communicate with each other. It is considered a "primitive" version of AOL's Instant Messenger, which came out the following year
On February 4, 2004, Zuckerberg launched Facebook from his Harvard dormitory room. An earlier inspiration for Facebook may have come from Phillips Exeter Academy, the prep school from which Zuckerberg graduated in 2002. It published its own student directory, "The Photo Address Book", which students referred to as "The Facebook". Such photo directories were an important part of the student social experience at many private schools. With them, students were able to list attributes such as their class years, their friends, and their telephone numbers.
Once at college, Zuckerberg's Facebook started off as just a "Harvard thing" until Zuckerberg decided to spread it to other schools, enlisting the help of roommate Dustin Moskovitz. They began with Columbia University, New York University, Stanford, Dartmouth, Cornell, University of Pennsylvania, Brown, and Yale. Samyr Laine, a triple jumper representing Haiti at the 2012 Summer Olympics, shared a room with Zuckerberg during Facebook's founding. "Mark was clearly on to great things," said Laine, who was Facebook's fourteenth user.
Zuckerberg, Moskovitz and some friends moved to Palo Alto, California in Silicon Valley where they leased a small house that served as an office. Over the summer, Zuckerberg met Peter Thiel, who invested in the company. They got their first office in mid-2004. According to Zuckerberg, the group planned to return to Harvard, but eventually decided to remain in California.
