The interaction of these forces of supply and demand in the marketplace can be depicted by combining the demand curve and the supply curve in a single graph. Only at the point at which the two curves intersect will the price/quantity desires of the buyers balance with the price/quantity desires of the sellers. The result is an equilibrium price and quantity set by the market forces of supply and demand.

I am a huge PC game online. In my thoughts I would think that I am the demand for better and more detailed games. And the supply lets say "Blizzard" is the supply for this games. Me as the demand wants these games at a reasible price, and it is up to the suppler "blizzard" to supply these games at that price. So we can find a equilibrium in the supply and demand graph.

According to (www.wikipedia.com)(2007) The supply and demand model describes the interaction in the market for a certain good between producers and consumers, in relation to the price and sales of the good. It is the fundamental model of microeconomics, and is used to explain a variety of microeconomic scenarios, as well as as a building block for many other economic models and theories. It was originally described by Antoine Augustin Cournot, and was popularized by Alfred Marshall.
