Facebook (stylized as facebook) is an American online social networking and social networking service based in Menlo Park, California, and the flagship service of Facebook, Inc. It was founded by Mark Zuckerberg along with fellow Harvard students and roommates. Eduardo Saverin, Andrew McCollum, Dustin Moskowitz and Chris Hughes.
Initially, the founders limited Facebook membership to Harvard students. Membership was expanded to Columbia, Stanford and Yale, and then expanded to the rest of the Ivy League, MIT and higher education institutions in the Boston area, then to other universities, and finally to high school students. Since 2006, anyone who claims to be 13 or older is allowed to become a registered Facebook user, although this may vary depending on local laws. The name comes from the Facebook guides that are often given out to American university students.
Facebook can be accessed from devices connected to the Internet, such as personal computers, tablets, and smartphones. After registration, users can create a profile that reveals information about themselves. They can post text, photos and media that they can share with any other users who have agreed to be their "friends", or, with different privacy settings, with any reader. Users can also use the various built-in apps, join groups with common interests, buy and sell products or services on the Marketplace, and receive notifications about their Facebook friends' activities and the Facebook pages they follow. Facebook claims to have over 2.3 billion monthly active users as of December 2018 [9] and was the most downloaded mobile app of the 2010s worldwide.

[39] On September 26, 2006, Facebook opened to anyone with a valid email address. [40] [41] [42] By the end of 2007, Facebook had 100,000 pages on which companies were promoting themselves. [43] The organization's pages began rolling out in May 2009. [44] On October 24, 2007, Microsoft announced that it had acquired a 1.6% stake in Facebook for $ 240 million, bringing Facebook's total estimated value to about $ 15 billion. Microsoft's purchase included international advertising rights. [45] [46]
In May 2007, at the first f8 developer conference, Facebook announced the launch of the Facebook Developer Platform, which provides software developers with a framework for building applications that interact with core Facebook functions. By the second annual conference of developers f8 on July 23, 2008, the number of applications on the platform had grown to 33,000, and the number of registered developers exceeded 400,000 [47].
In October 2008, Facebook announced that its international headquarters would be located in Dublin, Ireland. [48] In September 2009, Facebook reported that it had achieved positive cash flow for the first time. [49] A Compete.com study in January 2009 ranked Facebook as the most used social network among monthly active buy facebook users worldwide. [50]
In July 2010, the company announced 500 million users [51]. Half of the site's members used Facebook daily for an average of 34 minutes, while 150 million users visited the site on mobile devices. A company spokesman called the event a "quiet revolution." [52] In November 2010, according to SecondMarket Inc. (exchange for shares of private companies), Facebook was worth $ 41 billion. The company overtook eBay slightly to become the third largest US web company after Google and Amazon.com [53] [54].
