Wirehog was a friend-to-friend file sharing program that was linked to Facebook and allowed people to transfer files directly between computers.
History
Wirehog was created by Andrew McCollum, Mark Zuckerberg, Adam D'Angelo, and Sean Parker during their development of the Facebook social networking website in Palo Alto in the summer and fall of 2004. The only way to join Wirehog was through an invitation from a member and although it was originally planned as an integrated feature of Facebook, it could also be used by friends who were not registered on Facebook. Wirehog was launched in October 2004, and taken down in January 2006. Its target audience at the time was the same as the campus-only file-sharing service i2hub that had launched earlier that year. i2hub was gaining a lot of traction and growing rapidly. In an interview with The Harvard Crimson, Zuckerberg said, "I think Wirehog will probably spread in the same way that thefacebook did." During an early investing pitch to notable early Facebook seed round investors, Peter Thiel and Reid Hoffman in 2004, Hoffman told Zuckerberg to "abandon Wirehog" in favor of "thefacebook" project.
