Facebook, originally known as The Facebook, was launched 20 years ago and has gone through numerous redesigns. However, its core purpose of connecting people online and monetizing through advertising has remained unchanged throughout the years.
Since then, the world's most popular social network has been redesigned dozens of times. But its aim has remained the same: to connect people online. And make mountains of money from advertising.
Facebook quickly surpassed other existing social networks like MySpace and gained momentum shortly after its 2004 launch. The introduction of features such as photo tagging and a dynamic activity feed attracted early users, making it the leading platform in a short period.
Other social networks, such as MySpace, existed before Facebook - but Mark Zuckerberg's site instantly took off when it launched in 2004, proving just how rapidly an online site of this kind could take hold. In less than a year it had one million users, and within four years it had overtaken MySpace - fuelled by innovations such as the ability to "tag" people in photos.
While Facebook's popularity has decreased among young people, it remains the most popular social network globally. The company's expansion into less connected countries, along with the provision of free internet, has contributed to a rising user base, reaching 2.11 billion daily users in 2023.
By expanding into less connected countries and offering free internet, the company has maintained and increased the number of Facebook users. At the end of 2023, Facebook reported it had 2.11 billion daily users.
