When the first iteration of Facebook launched on February 4, 2004, few likely predicted that the website would go on to fundamentally change the way the world communicates and interacts.
The first version of the site, back when it was called The Facebook, was a Harvard-only site. Eventually, though, the site would open up to other Ivy League schools before expanding to other universities, and finally to the world at large. Interestingly, the original home page retains many of the design elements that currently exist on the present site. As a point of interest, legend has it that the man in the upper left is a composite and altered photo of Al Pacino.
