LinkedIn Learning is an American online learning platform. It provides video courses taught by industry experts in software, creative, and business skills. It is a subsidiary of LinkedIn. All the courses on LinkedIn fall into four categories: Business, Creative, Technology, and Certifications. It was founded in 1995 by Lynda Weinman as Lynda.com before being acquired by LinkedIn in 2015 and becoming LinkedIn Learning. Microsoft acquired LinkedIn in December 2016. LinkedIn Learning was founded as Lynda.com in 1995 in Ojai, California, as online support for the books and classes of Lynda Weinman, a special effects animator and multimedia professor who founded a digital arts school with her husband, artist Bruce Heavin. In 2002, the company began offering courses online. By 2004, there were 100 courses, and in 2008, the company began producing and publishing documentaries on creative leaders, artists, and entrepreneurs. In 2013, Lynda.com received its first outside investment, raising 186 million in financing, led by investment group TPG Capital. On April 9, 2015, LinkedIn announced its intention to buy Lynda.com in a deal valued at 26.2 billion. The acquisition was completed on December 8, 2016. In October 2017, Lynda.com was merged and renamed LinkedIn Learning. In 2019, the site announced that users accessing LinkedIn Learning through their public library would be required to create a LinkedIn profile in order to use the service; the decision faced criticism from librarians and the American Library Association. As of March 2021, libraries started migrating to LinkedIn Learning without requiring patrons to create a LinkedIn profile.
