The unauthorized
copying of
software. Most retail
programs are
licensed for use at just one
computer site or for use by only one
user at any time. By buying the software, you become a
licensed user rather than an owner (see
EULA). You are allowed to make copies of the program for
backup purposes, but it is against the law to give copies to friends and colleagues.
Software piracy is all but impossible to stop, although software companies are launching more and more lawsuits against major infractors. Originally, software companies tried to stop software piracy by
copy-protecting their software. This strategy failed, however, because it was inconvenient for users and was not 100 percent foolproof. Most software now requires some sort of registration, which may discourage would-be pirates, but doesn't really stop software piracy.
Some common types of software piracy include
counterfeit software,
OEM unbundling, softlifting,
hard disk loading,
corporate
software piracy, and Internet
software piracy.
An entirely different approach to software piracy, called
shareware, acknowledges the futility of trying to stop people from copying software and instead relies on people's honesty. Shareware publishers encourage users to give copies of programs to friends and colleagues but ask everyone who uses a program regularly to pay a registration fee to the program's author directly.
Commercial programs that are made available to the public illegally are often called
warez.
