History and evolution of social networks

The first identifiable forms of social networking appeared in the 1970s and 1980s. However, the modern concept of social networking as we know it today really took off in the mid-2000s with the launch of sites such as MySpace and Facebook.

The main objective of the first prominent social networking sites was professional networking. Six Degrees, for example, started in 1997 and allowed users to post a profile and connect with friends. However, it was not well received and the company went bankrupt in 2000.

Social networking services such as MySpace and Facebook began to gain traction in the mid-2000s, especially among young people. Users could create a personal profile, connect with friends and exchange content such as pictures and news about their lives on these sites.

As social networking has progressed, new platforms with unique features and functions have emerged. Twitter, for example, started in 2006 and allows users to send short messages (called «tweets») to a wide audience. Instagram is a photo- and video-sharing network that debuted in 2010, while TikTok is a short video platform that debuted in 2016.
