TheFacebook was the name of Facebook’s 2004 student directory website before it became Facebook.
Mark Zuckerberg launched the service at Harvard University on February 4, 2004, using the original name “TheFacebook.” It was designed as an online directory modeled on printed student facebooks, which displayed photographs and basic information about students. Access initially focused on Harvard students and later expanded to other universities.
The service dropped “The” from its name in August 2005, becoming Facebook. The domain Facebook.com was acquired during that period, helping establish the shorter brand that became internationally known. The name change is separate from the company’s 2021 rebrand to Meta, which affected the parent corporation rather than the Facebook product.
Some accounts refer to the original service simply as “Facebook,” but “TheFacebook” is the specific early name used at launch. That distinction matters because the question asks for the original website name, not the later shortened brand.
