LinkedIn

LinkedIn is a business- and employment-oriented social networking service that operates via websites and mobile apps.  Founded on December 28, 2002, and launched on May 5, 2003, it is mainly used for professional networking, including employers posting jobs and job seekers posting their CVs. As of 2015, most of the company's revenue came from selling access to information about its members to recruiters and sales professionals. As of April 2017, LinkedIn had 500 million members in 200 countries, out of which more than 106 million members are active. LinkedIn allows members (both workers and employers) to create profiles and "connections" to each other in an online social network which may represent real-world professional relationships. Members can invite anyone (whether an existing member or not) to become a connection.
According to the New York Times, US high school students are now creating LinkedIn profiles to include with their college applications. Based in the United States, the site is, as of 2013, available in 24 languages, including Arabic, Chinese, English, French, German, Italian, Portuguese, Spanish, Dutch, Swedish, Danish, Romanian, Russian, Turkish, Japanese, Czech, Polish, Korean, Indonesian, Malay, and Tagalog.
