LinkedIn (/lɪŋktˈɪn/) is an American business and employment-oriented online service that operates via websites and mobile apps. Launched on May 5, 2003,[4] 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.[5] Since December 2016, it has been a wholly owned subsidiary of Microsoft.
