I have heard people question how Facebook can support 500 million accounts and remain free to users. Some people have even held the absurd notion that Facebook will charge users one day.

Funding Facebook is something that most users don’t give a lot of thought to, as they connect and have fun with their friends. Most people will easily overlook the huge volume of advertisement dollars Facebook generates from their ads. Advertising is a common business model of most of the popular Internet (REF: Google, YouTube, Facebook, and etcetera), and it works extremely well. It is how Facebook makes money, and those advertisements facilitate Facebook’s bloated $50 Billion valuation in January 2011.
