<h2 id="facebooks-social-graph">Facebook's social graph</h2> <p>As of 2010<a href="https://en.wikipedia.org/w/index.php?title=Social_graph&action=edit">[update]</a>, Facebook's social graph is the largest <a href="/facts/Social_network/kQg6aEVf">social network</a> dataset in the world,<a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a> and it contains the largest number of defined relationships between the largest number of people among all websites because it is the most widely used social networking service in the world.<a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a> </p> <h3>Issues</h3> <p>Several issues have come forward regarding the existing implementation of the social graph owned by Facebook. For example, currently, a social networking service is unaware of the relationships forged between individuals on a different service. This creates an online experience that is not seamless, and instead provides for a fragmented experience due to the lack of an openly available graph between services. In addition, existing services define relationships differently. </p><p>Concern has also focused on the fact that Facebook's social graph is owned by the company and is not shared with other services, giving it a major advantage over other services and preventing its users from taking their graph with them to other services when they wish to do so, such as when a user is dissatisfied with Facebook. <a href="/facts/Google/GT9Sugza">Google</a> has attempted to offer a solution to this problem by creating the Social Graph API, released in January 2008,<a class="footnote-ref" id="fnref:8" href="#fn:8"><sup>8</sup></a> which allows websites to draw publicly available information about a person to form a portable identity of the individual, in order to represent a user's online identity.<a class="footnote-ref" id="fnref:9" href="#fn:9"><sup>9</sup></a> This did not, however, experience Google's desired uptake and was thus retired in 2012.<a class="footnote-ref" id="fnref:10" href="#fn:10"><sup>10</sup></a> Facebook introduced its own Graph API at the 2010 f8 conference. Both companies monetise collected data sets through <a href="/facts/Direct_marketing/D8pfbbyR">direct marketing</a> and <a href="/facts/Social_commerce/ENNAyEKS">social commerce</a>.<a class="footnote-ref" id="fnref:11" href="#fn:11"><sup>11</sup></a> In December 2016, Microsoft acquired <a href="/facts/LinkedIn/Iq2IcNMt">LinkedIn</a> for $26.2 billion.<a class="footnote-ref" id="fnref:12" href="#fn:12"><sup>12</sup></a> </p> <h2 id="open-graph">Open Graph</h2> <p class="note">Further information: <a href="/facts/Facebook_Platform/IoHpQE94">Facebook Platform § Open Graph protocol</a></p> <p>Facebook's Graph API allows websites to draw information about more objects than simply people, including photos, events, and pages, and their relationships between each other. This expands the social graph concept to more than just relationships between individuals and instead applies it to virtual non-human objects between individuals, as well.<a class="footnote-ref" id="fnref:13" href="#fn:13"><sup>13</sup></a> </p> <h2 id="see-also">See also</h2> <ul><li><a href="/facts/Social_network/kQg6aEVf">Social network</a></li> <li><a href="/facts/List_of_social_networking_websites/xDBVmcb8">List of social networking websites</a></li> <li><a href="/facts/Social_network_analysis/CsJIFjVw">Social network analysis</a></li> <li><a href="/facts/Social_network_analysis_software/qwUze2If">Social network analysis software</a></li> <li><a href="/facts/Social_web/I3vjvJ1C">Social web</a></li> <li><a href="/facts/Sociomapping/k9HHXl2C">Sociomapping</a></li> <li><a href="/facts/Sociometry/2k3HHN5L">Sociometry</a></li></ul> <ul><li><a href="/facts/Jacob_L._Moreno/rCzMR2ua">Jacob L.
