    Facebook is a social networking website that allows people to communicate with their friends and exchange information. Launched on February 4, 2004, Facebook was founded by Mark Zuckerberg, a former member of the Harvard Class of 2006 and former Ardsley High School student. Initially the membership was restricted to students of Harvard College. It was subsequently expanded to other Boston area schools (Boston College, Boston University, Harvard, Northeastern University, Tufts University), Rochester, Stanford, NYU, Northwestern, and all Ivy League schools within two months. Many individual universities were added in rapid succession over the next year. Eventually, people with a university (e.g .edu, .ac.uk, etc.) email address from institutions across the globe were eligible to join. Networks were then initiated for high schools and some large companies. Since September 11, 2006, it has been made available to any email address[2] user who inputs a certain age range. Users can select to join one or more participating networks, such as a high school, place of employment, or geographic region.

    As of July 2007, the website had the largest number of registered users among college-focused sites with over 34 million active members worldwide (also from non-collegiate networks).[3] From September 2006 to September 2007[4] it increased its ranking from 60th to 7th most visited web site, and was the number one site for photos in the United States, ahead of public sites such as Flickr, with over 8.5 million photos uploaded daily.[5][6]

    The name of the site refers to the paper facebooks depicting members of the campus community that U.S. colleges and preparatory schools give to incoming students, faculty, and staff as a way to get to know other people on campus.

    Operations

    The site is free to users and generates revenue from advertising including banner ads and sponsored groups (in April 2006, revenue was rumored to be over $1.5 million per week).[7] Users create profiles that often contain photos and lists of personal interests, exchange private or public messages, and join groups of friends. The viewing of detailed profile data is restricted to users from the same network or confirmed friends. According to TechCrunch, "about 85% of students in [previously] supported colleges have a profile [on the site]. [Of those who are signed up,] 60% log in daily. About 85% log in at least once a week, and 93% log in at least once a month." According to Chris Hughes, spokesman for Facebook, "People spend an average of 19 minutes a day on Facebook."[8] In a 2006 study conducted by Student Monitor, a New Jersey-based limited liability company specialising in research concerning the college student market, Facebook was named as the second most "in" thing among undergraduates, tied with beer and sex and losing only to the iPod.[9]
