Summary. Call of Duty 2 is a realistic World War II game created for mobile devices. The storyline closely follows Activision and Infinity Ward's hit console game.

Monopolies. The word monopoly is derived from Greek words meaning one seller.  If one company is the only manufacturer of a product, that company has a monopoly. It is able to set its own quality standards and establish selling prices. It can also control middlemen, such as wholesalers and truckers.

Under a monopoly, only one firm offers a product or service, experiences no competition, and sets the price, thus making it a price maker rather than a price taker.
