Enterprise social networking focuses on the use of online social networks or social relations among people who share business interests and/or activities. Enterprise social networking is often a facility of enterprise social software (regarded as a primary component of Enterprise 2.0), which is essentially social software used in "enterprise" (business/commercial) contexts. It encompasses modifications to corporate intranets (referred to as social intranets) and other classic software platforms used by large companies to organize their communication, collaboration and other aspects of their intranets. Enterprise social networking is also generally thought to include the use of a standard external social networking service to generate visibility for an enterprise. History Social networking sites started to form in the 1990s; an example of these websites is Theglobe.com, which began in 1995. As other websites such as GeoCities and Tripod.com started to form online communities, they encouraged their users to interact with each other via chat rooms and other tools. They also provided easy-to-use publishing tools along with free web space. Classmates.com’s approach was to link people together via their emails, the website was like a friends search engine. Businesses eventually realized that social networking websites could provide a fast and efficient way of marketing. Social media websites are great places for businesses to reach their customers, and the environment can provide a means for growing a business. In 2005, as social networking websites were becoming more and more popular, Myspace had more page views than Google. Myspace was followed by Facebook which started in February 2004. When Facebook began, users were limited to college students in the United States, who had to use a college email with a .edu extension to join the network. In September 2005 some high schools were allowed to join the network, but they needed an invitation to join. On September 26 of 2006, Facebook announced that anyone around the world older than 13 years old with a valid email would be able to join Facebook’s online community. In October 2007, Microsoft purchased a 1.6% share of Facebook. That gave them the right to place international ads on Facebook. In July 2010 it was reported that Facebook had more than 500 million active users. This means that one out of fourteen people around the world is a Facebook user. The growth of Facebook was a boom in the social networking space. Facebook became a huge corporation that had 1400 employees
