LinkedIn is a social media platform designed primarily for professional use. Created in 2002 and launched in 2003, LinkedIn allows users to create profiles and connections so that an online professional network can be managed. The network allows members to share ideas, keep up with industry trends, post and find jobs, and expand their professional network.

Origin, History and Evolution of LinkedIn

LinkedIn was founded in December 2002 by Reid Hoffman, a Silicon Valley entrepreneur who had previously worked for PayPal and, among other companies. Hoffman recruited a team of former Socialnet colleagues and PayPal to work on the new company. The LinkedIn page was launched to the public on May 5, 2003.

In its early years, LinkedIn grew slowly compared to other social networks. However, it remained steadfast in its focus on professional networking, avoiding the temptation to expand into the social areas that were driving the rapid growth of other networks like Facebook.

As the economy became increasingly digital and the need for a professional online presence became more apparent, LinkedIn began to grow more rapidly. It added new features, such as the ability to follow companies and search for employment, and also expanded internationally.

In 2011, LinkedIn became the first social network in the United States to go public, which was an important milestone in its history.


LinkedIn has evolved from simply a networking network to a one-stop platform for professionals. It now offers a variety of features, including discussion groups, blog posts, online training (via LinkedIn Learning), and CRM (customer relationship management) features.

In 2016, Microsoft acquired LinkedIn for $26.2 billion, the largest acquisition in Microsoft's history to date. Under Microsoft's ownership, LinkedIn has continued to expand its features and grow in users.

In 2021, LinkedIn reported more than 774 million users in more than 200 countries and territories worldwide. It continues to be an essential platform for professionals looking to network, learn, share knowledge and find job opportunities.
