Professional networking platform connecting over 1 billion members globally.
LinkedIn is an American social networking platform focused on business and employment, used worldwide. It launched on May 5, 2003, founded by Reid Hoffman and Eric Ly, with early financial backing from venture capital firms like Sequoia Capital. The service is mainly used for professional networking and career growth: job seekers can upload their CVs, while employers can advertise job openings. By July 2023, LinkedIn had over 1 billion registered members across more than 200 countries and territories. Users can invite others to become connections, even if those people are not yet members. As the platform grew, its role expanded beyond recruiting into a key tool for professionals and entrepreneurs to build visibility and authority. It also allows users to organize offline events, create and join groups, write articles, and share photos and videos.
In 2007, with 10 million users, LinkedIn opened offices in India, Australia, and Ireland. By October 2010, Silicon Valley Insider ranked it No. 10 on its Top 100 List of most valuable startups. From 2015 onward, most of its revenue came from selling access to member data to recruiters and sales professionals; it also launched LinkedIn Ads for companies to advertise on the platform. In December 2016, Microsoft bought LinkedIn for $26.2 billion, its largest acquisition at the time. Since 2017, 94% of business-to-business marketers have used LinkedIn to distribute content.
LinkedIn has faced criticism for design choices, such as its endorsement feature and using members' email accounts to send spam. Security issues have occurred: in 2012, cryptographic hashes of about 6.4 million users were stolen and published online; in 2016, 117 million usernames and passwords (likely from the 2012 breach) were offered for sale. The platform has also been criticized for mishandling misinformation and disinformation, especially regarding the COVID-19 pandemic and the 2020 US presidential election. Several countries have banned or restricted LinkedIn: Russia in 2016, Kazakhstan in 2021, and China in 2021.

Reader's Guide
LinkedIn's significance lies in its transformation of professional networking from a resume-posting service into a primary channel for career development, authority-building, and business-to-business marketing. Since 2017, 94% of B2B marketers have used LinkedIn to distribute content. Its acquisition by Microsoft integrated the platform with Office products, though it retained its distinct brand and independence. The platform's global reach—over 1 billion members across 200 countries—has made it essential for recruiters, sales professionals, and entrepreneurs. However, its legacy is tempered by persistent security vulnerabilities and content moderation challenges, including bans in multiple countries for non-compliance with data storage laws and misinformation issues. LinkedIn's evolution from a startup valued at $1.575 billion in private markets in 2010 to a $26.2 billion acquisition illustrates its central role in the digital economy.
