College students have long played an integral role in the development and adoption of new technology. Students, along with businesspeople, comprised the bulk of the portable electric typewriter market in the 1960s and 1970s. In the mid-1970s, two students – Bill Gates and Steve Ballmer – met while living in the same hall at Harvard, and went on to play critical roles in the development of the personal computer in the 1980s and 1990s. Universities were among the first institutions to support the growth of the internet, and for a time provided high-speed internet access to more people than did corporations. In the late 1990s, a Northeastern University student named Shawn Fanning and his uncle developed Napster, one of the first popular peer-to-peer file sharing programs. Again at Harvard, Mark Zuckerberg and fellow computer science majors developed Facebook, which was initially only available to college students, but now is the second most-trafficked website, after Google. Google itself was born through the collaboration of two Stanford University graduate students, Larry Page and Sergey Brin.
