LinkedIn profile

LinkedIn launched on May 5, 2003, founded by Reid Hoffman and a team of colleagues from SocialNet and PayPal. The platform grew from roughly 4,500 members at the end of its first month to over one billion users by the 2020s, spanning more than two hundred countries. Microsoft acquired the company in 2016 for approximately $26.2 billion, the largest acquisition in Microsoft's history at that time.

The profile template standardized how professionals present themselves. A headline, a summary, a chronological list of positions with descriptions, skills endorsed by connections, and recommendations from colleagues. The format created a public, searchable version of the resume, visible not just to prospective employers but to current colleagues, former classmates, and the broader professional world. The result was a new kind of professional performance, one in which the curation of a career narrative became a continuous obligation rather than an occasional task.

The platform also formalized networking as a quantifiable activity. Connections could be counted, endorsements accumulated, and content engagement measured. The phrase "building your personal brand," once associated with marketing consultants, became a standard expectation for professionals across industries. LinkedIn made visible what the industrial system had always implied, that a worker's value is not inherent but performed, and that the performance never stops.
