History Of Facebook

        Facebook is a social networking service launched in February 2004, owned and operated by Facebook, Inc.^[5] As of September 2012, Facebook has over one billion active users,^[6] more than half of them using Facebook on a mobile device.^[7] Users must register before using the site, after which they may create a personal profile, add other users as friends, and exchange messages, including automatic notifications when they update their profile. Additionally, users may join common-interest user groups, organized by workplace, school or college, or other characteristics, and categorize their friends into lists such as "People From Work" or "Close Friends".

              Mark Zuckerberg wrote Facemash, the predecessor to Facebook, on October 28, 2003, while attending Harvard as a sophomore. According to The Harvard Crimson, the site was comparable to Hot or Not, and "used photos compiled from the online facebooks of nine houses, placing two next to each other at a time and asking users to choose the 'hotter' person"

             

To accomplish this, Zuckerberg hacked into the protected areas of Harvard's computer network and copied the houses' private dormitory ID images. Harvard at that time did not have a student "facebook" (a directory with photos and basic information), though individual houses had been issuing their own paper facebooks since the mid-1980s. Facemash attracted 450 visitors and 22,000 photo-views in its first four hours online.^[18][20]

The site was quickly forwarded to several campus group list-servers, but was shut down a few days later by the Harvard administration. Zuckerberg was charged by the administration with breach of security, violating copyrights, and violating individual privacy, and faced expulsion. Ultimately, the charges were dropped.^[21] Zuckerberg expanded on this initial project that semester by creating a social study tool ahead of an art history final, by uploading 500 Augustan images to a website, with one image per page along with a comment section.^[20] He opened the site up to his classmates, and people started sharing their notes.

The following semester, Zuckerberg began writing code for a new website in January 2004. He was inspired, he said, by an editorial in The Harvard Crimson about the Facemash incident.^[22] On February 4, 2004, Zuckerberg launched "Thefacebook", originally located at thefacebook.com.^[23]

     Six days after the site launched, three Harvard seniors, Cameron Winklevoss, Tyler Winklevoss, and Divya Narendra, accused Zuckerberg of intentionally misleading them into believing he would help them build a social network called HarvardConnection.com, while he was instead using their ideas to build a competing product.^[24] The three complained to the Harvard Crimson, and the newspaper began an investigation. The three later filed a lawsuit against Zuckerberg, subsequently settling.^[25]

Membership was initially restricted to students of Harvard College, and within the first month, more than half the undergraduate population at Harvard was registered on the service.^[26] Eduardo Saverin (business aspects), Dustin Moskovitz (programmer), Andrew McCollum (graphic

artist), and Chris Hughes soon joined Zuckerberg to help promote the website. In March 2004, Facebook expanded to Stanford, Columbia, and Yale.^[27] It soon opened to the other Ivy League schools, Boston University, New York University, MIT, and gradually most universities in Canada and the United States.^[28][29]

Facebook was incorporated in mid-2004, and the entrepreneur Sean Parker, who had been informally advising Zuckerberg, became the company's president.^[30] In June 2004, Facebook moved its base of operations to Palo Alto, California.^[27] It received its first investment later that month from PayPal co-founder Peter Thiel.^[31] The company dropped The from its name after purchasing the domain name facebook.com in 2005 for $200,000.^[32]
