Facebook was born at Harvard University in the United States. The social network was launched on February 4, 2004 from Mark Zuckberg's small room. The idea was simple but revolutionary to create a new way of sharing day-to-day experiences.

This is how the concept of 'Facebook friend' was created, which in the future would inspire new social networks such as Twitter

At first, Facebook was used internally among the same University students. Within a month of life, 50% of Harvard students were already enrolled. At that time, 'The Facebook' began to enable other Universities such as Columbia and Stanford.

Interest in the community of these universities grew considerably and at the end of 2004 the social network is open to almost all universities in the US and Canada with around one million users. but over time anyone with an email account could access 

2005 is one of the key years for Facebook. First, the social network loses the "The" and becomes officially and only on Facebook adds new functions such as tagging people in photos. second, Facebook opens its doors to more users and allows high school students and universities from other countries (Mexico, United Kingdom, Ireland, Australia) to access the social network. At the end of the year, Facebook already had around 6 million active users

Five years after the website was created, on February 9, 2009 Facebook activates the iconic "like" button. In that year Facebook became the most famous platform in the world with 350 million registered users and 132 million unique monthly users.
