Everyone knows how big Facebook has become. Everyone is practically on the social networking site two,three, or even one hundred times a day. The only thing people are still questioning is how much the company makes in revenue. The question has been in the air ever since Microsoft invested millions into the company CEO Mark Zuckerberg started.

On monday, Marc Andreessen, Facebook board member, said in an interview with Reuters that he is expecting the social networking site to bring in over $500 million by the year end. He also said that he predicts the company to be bringing in billions in the next five years to come.

Ad sales seem to be the companies main revenue. It is usually many sites main revenue and it could make or break a company. Andreessen even said in his interview that if the company worked harder in it’s advertising sales, it could be profiting in the billions. Facebook is working towards other revenue streams which include a system based on credits like it’s Gifts application. It hopes to turn this into something where people can purchase and make transactions on any fun new ideas.
