There are many rumors being spread that Facebook is going to start charging its users an additional fee for membership. The real question is why would anyone want to pay for something that they could get for free on Google, Twitter, MySpace or any other social networking site? Facebook’s’ main goal is to connect everyone in the world. If one had to pay, it would be leaving out millions of people that weren’t able to afford a membership no matter what the cost may be. This idea is a great indicator of supply and demand. The demand for Facebook has skyrocketed since it started in 2004. In one day, half a billion people have used the website. Facebook’s business model completely revolves around having as many users as possible. The company realized that they can’t reach their ultimate goal if they charge users. Also, the idea of charging users is a perfect example of opportunity cost. Creators are giving up potential revenue that they could receive, for the need of masses of users to fuel their company to be successful. One final example of charging users is the idea of a tradeoff for the company. Facebook doesn’t need any money at this point because they are bringing 4 billion in revenue this year, raising more than 2 billion in venture capital. In 2012, the company is expected to be with 100 billion. They have chosen to make their money by advertising, Facebook credits, and social games such as Farmville and Mafia wars. Eventually they may charge for subscriptions to music and TV services, but it wouldn’t make sense to charge a user to their personal account.
