Copyright regulates all kinds of reproducing of copyrighted information - copying, translating, broadcasting, etc. The goal of the copyright law is to protect original creators of intellectual property. Once an original work is created, it is automatically considered to be copyrighted. The owner can then give up some or all rights to his intellectual property to someone else. After the expiration of the copyright, it is transfered to the public domain. but even after the expiration of the copyright, giving credit is advisable.
Fair use doctrine 1976 - "permitted the moderate use of copyrighted materials for purposes such as education, news reporting, criticism, parody, and even (in some contexts) home consumption, as long as those activities did not substantially impair the copyright owners’ abilities to exploit “potential markets.”"
