Facebook

Facebook (stylized as facebook ) is an American online social media and social networking service based in Menlo Park, California, and a flagship service of the namesake company Facebook, Inc. It was founded by Mark Zuckerberg, along with fellow Harvard College students and roommates Eduardo Saverin, Andrew McCollum, Dustin Moskovitz, and Chris Hughes. The founders of Facebook initially limited membership to Harvard students. Membership was expanded to Columbia, Stanford, and Yale before being expanded to the rest of the Ivy League, MIT, and higher education institutions in the Boston area, then various other universities, and lastly high school students. Since 2006, anyone who claims to be at least 13 years old has been allowed to become a registered user of Facebook, though this may vary depending on local laws. The name comes from the face book directories often given to American university students. Facebook can be accessed from devices with Internet connectivity, such as person

History

2003–2006: Thefacebook, Thiel investment, and name change Zuckerberg built a website called "Facemash" in 2003 while attending Harvard University. The site was comparable to Hot or Not and used "photos compiled from the online face books of nine Houses, placing two next to each other at a time and asking users to choose the "hotter" person". Facemash attracted 450 visitors and 22,000 photo-views in its first four hours. The site was sent to several campus group listservs, but was shut down a few days later by Harvard administration. Zuckerberg faced expulsion and was charged with breaching security, violating copyrights and violating individual privacy. Ultimately, the charges were dropped. Zuckerberg expanded on this project that semester by creating a social study tool ahead of an art history final exam. He uploaded all art images to a website, each of which was accompanied by a comments section, then shared the site with his classmates. A "face bo

Technical aspects This section's factual accuracy may be compromised due to out-of-date information . The reason given is: Facebook no longer uses HipHop for PHP. Please update this article to reflect recent events or newly available information. ( August 2020 ) The website's primary color is blue as Zuckerberg is red–green colorblind, a realization that occurred after a test undertaken around 2007. Facebook is built in PHP, compiled with HipHop for PHP, a "source code transformer" built by Facebook engineers that turns PHP into C++. The deployment of HipHop reportedly reduced average CPU consumption on Facebook servers by 50%. 2012 architecture Facebook is developed as one monolithic application. According to an interview in 2012 with Facebook build engineer Chuck Rossi, Facebook compiles into a 1.5 GB binary blob which is then distributed to the servers using a custom BitTorrent-based release system. Rossi stated that it takes about 15 minutes to build and 15 minu

Criticisms and controversies

Facebook's importance and scale has led to criticisms in many domains. Issues include Internet privacy, excessive retention of user information, its facial recognition software, its addictive quality and its role in the workplace, including employer access to employee accounts. Facebook is alleged to have psychological effects, including feelings of jealousy and stress, a lack of attention and social media addiction. European antitrust regulator Margrethe Vestager stated that Facebook's terms of service relating to private data were "unbalanced". Facebook has been criticized for electricity usage, tax avoidance, real-name user requirement policies, censorship and its involvement in the United States PRISM surveillance program. Facebook has been criticized for allowing users to publish illegal and/or offensive material. Specifics include copyright and intellectual property infringement, hate speech, incitement of rape and terrorism, fake news, and crimes, murders, and

Scope A commentator in The Washington Post noted that Facebook constitutes a "massive depository of information that documents both our reactions to events and our evolving customs with a scope and immediacy of which earlier historians could only dream". Especially for anthropologists, social researchers, and social historians—and subject to proper preservation and curation—the website "will preserve images of our lives that are vastly crisper and more nuanced than any ancestry record in existence". Economy Economists have noted that Facebook offers many non-rivalrous services that benefit as many users as are interested without forcing users to compete with each other. By contrast, most goods are available to a limited number of users. E.g., if one user buys a phone, no other user can buy that phone. Three areas add the most economic impact: platform competition, the market place and user behavior data. Facebook began to reduce its carbon impact after Greenpeace a
