It's hard to believe, but there was a time when Facebook was not a daily part of our lives.

Back in 2004, the social networking site was in its infancy, merely a presence on the college circuit. Fast forward 11 years later and it's become as much an ingrained part of society as people spewing their political beliefs on Facebook.

CNBC unveiled a clip of Mark Zuckerberg explaining just what Facebook is and what he hopes to do with it back in an interview he did in 2004 when he was still at Harvard and the site, still known as The Facebook, had a tiny-by-today's-standards 100,000 users. You know, before everyone on the planet (even your parents) signed on.

11 years ago today, someone named Mark Zuckerberg appeared on CNBC to discuss a social network that had 100,000 users.

It's fascinating to watch this knowing Facebook has basically transformed our day-to-day lives. Think about it: in 2004, it was still unheard of to plausibly accept there would be a destination to see what the kid who sat behind you in 9th grade algebra thinks about gay marriage or look at a photo of what your ex-girlfriend ate for dinner last night. But that's the world we now live in.

It's a pretty interesting clip. About the only thing more interesting is finding out who exactly is getting the split screen treatment with Zuckerberg. We'd like to find out so we can friend him.
