Shareware
Shareware is often referred to as trialware or demoware. Shareware is software that is distributed for free on a trial basis. The software will have a combination of restrictions based on convenience, functionality and availability. A shareware program can, for example, be free for 10 days but have a large amount of ads or promotions that break up the use of the program. The user will able to pay money for a full license to the program, which will give full functionality and remove any of the restrictions that were there in the free version. Shareware is distributed through downloads on a website or through free compact discs in magazines and newspapers. This is done in order to avoid selling the product at a store and giving the end-user a reduced price for the product. Blizzard has offered its World of Warcraft game as shareware, giving trial versions in boxes of their other games. After two weeks of activation, the trial expires and gives the user an ability to purchase a full version of the game, without having to purchase it from a store such as Best Buy or any other store that sells software
