Facebook is a social media created on February 4, 2004, initially as a free university service and later expanded for commercial purposes, owned and operated by the company Meta, Inc., and based on a web 2.0 platform written in various programming languages.

The social network, founded at Harvard University in the United States by Mark Zuckerberg, Eduardo Saverin, Andrew McCollum, Dustin Moskovitz and Chris Hughes, was originally designed exclusively for students of that university, but was soon opened to students of other Boston area schools, the Ivy League and Stanford University.

Subsequently it was also opened to high school students, and then to anyone claiming to be over 13 years of age, achieving enormous global success and profoundly changing many aspects related to socialization and interaction between individuals, both privately and on a social level. the economic and commercial one.

Recently, millions of users use Facebook as a platform similar to YouTube, or to showcase their videos, creating a virtual community among their subscribers. Facebook is not only designed for natural persons and their private life but, through a dedicated service, it is also a social marketing tool.
