Which company was founded by Mark Zuckerberg in 2004?
Answer
Answer
Mark Zuckerberg founded Facebook in 2004.
Zuckerberg launched the site as TheFacebook on February 4, 2004, while he was a student at Harvard College. It began as a social directory for Harvard students, allowing users to create profiles and connect with classmates. The service soon expanded to other universities in the United States and Canada.
Zuckerberg was not the sole founder. Eduardo Saverin, Dustin Moskovitz, Andrew McCollum, and Chris Hughes were also early co-founders and collaborators. Zuckerberg’s role was central, but the wording “founded by Mark Zuckerberg” remains accurate because it identifies the company’s principal founder without claiming he worked alone.
The company dropped “The” from its name in 2005 after acquiring the Facebook.com domain. Early investor Peter Thiel provided important funding, while former Napster executive Sean Parker became the company’s first president. Facebook later grew from a college network into a global platform and, in 2021, its parent company was renamed Meta Platforms.
