Copyright is the right for the creator of something to be the only one to reproduce, sell, or publish his or her own product such as a book, movie, picture, etc. However people cannot copyright an idea but the form it takes such as being a book or movie. The fair use act allows people to use a small amount of a copyrighted product for teaching, criticism, or research. The public domain is a place where products that are no longer copyrighted can be used by other people. The copyright time period is now longer then before and can last up to 70 to 100 years. People can use a copyright product if they ask permission, pay the copyright owner, or use it under the fair use act or creative commons license. A creative commons license allows the copyright holder to dictate if others can use their work. They keep their copyright, but others can copy and distribute work as long as credit is given to the copyright holder.
