A copyright is a bundle of rights exclusively for the author of an original work. It includes rights of adaptation, reproduction and translation of the work. Also the right for communication to the public.
Copyright has the same value in cyberspace as in the other forms of publishing like books, CDs, newspapers etc. Everything online - news, stories, software, novels, blogs, screenplays, graphics, pictures, Usenet messages and even e-mails - are protected by copyright laws for the Internet.
The Internet Copyright Laws state that the copyright protection expires 70 years after the death of the author. In the case of "work for hire" (where work is the copyright of an employer), the copyright holds for 95 years.
