Fair use
Since a lot of creative work is now on computers and on the Internet, it is very easy to copy things and send them to lots of people. To make sure that people cannot always do this, there are computer programs that try to stop people from copying other people's work (known as digital rights management). One problem with these programs is that they also mean that you cannot copy even a small part of someone's work, so you cannot do "fair use" without cheating the program. In some countries, cheating those software programs is also breaking the law.
