Which company operates the LinkedIn professional networking service?

Microsoft operates LinkedIn after acquiring the professional networking company in 2016.

LinkedIn was founded in 2003 by Reid Hoffman and other co-founders, and the website launched in May of that year. It connects professionals, recruiters, employers, educators, and job seekers. Users can maintain profiles, publish posts, list skills, advertise vacancies, and complete courses through LinkedIn Learning.

Microsoft announced its agreement to buy LinkedIn for $26.2 billion in June 2016, and the acquisition was completed later that year. LinkedIn continues to use its own brand and service identity rather than becoming a feature called Microsoft LinkedIn. The acquisition expanded Microsoft’s business software and professional-data ecosystem.
