software piracy = The illegal copying of software for distribution within the organization, or to friends, clubs and other groups, or for duplication and resale. The software industry loses billions of dollars each year to piracy, and although it may seem innocent enough to install an application on a couple of additional machines, it may ultimately shatter the profitability of a small software company. Software piracy is a major issue in the U.S. and Europe, but it is rampant in the rest of the world where major applications are routinely copied for resale. ‘Software Police' are cracking down hard and the penalties are harsh. ‘Softlifting' recently became a felony with penalties of up to $250,000 and five years in jail.
