Which social network launched in 2004?

The story behind the answer

Which social network launched in 2004? Facebook did. Mark Zuckerberg and fellow Harvard students launched the service on February 4, 2004, originally under the name TheFacebook. It began as a Harvard-only directory, allowing students to create profiles and connect with classmates.

Access soon expanded to other Ivy League universities, then to colleges across the United States and Canada. By September 2006, Facebook was open to anyone aged 13 or older with a valid email address. This gradual expansion helped it grow from a campus networking tool into a global social platform.

A common mix-up is confusing Facebook’s launch with the founding dates of other major networks. LinkedIn launched in 2003, MySpace in 2003, and Twitter in 2006. Facebook’s original name also sometimes causes confusion, but the service itself is universally known as Facebook.
