Software piracy costs the information technology industry billions of dollars in lost sales each year. This chapter presents an overview of the software piracy issue, including a review of the ethical principles involved and a summary of the latest research. In order to better illustrate some of the material presented, the results of a small research study in the country of Jordan are presented. The findings indicate that piracy among computer-using professionals is high, and that cost is a significant factor in the decision to pirate. Finally, some potential preventative mechanisms are discussed, in the context of the material presented previously in the chapter.
