The nature of copyright can exist in almost every medium whether as photographs, framed paintings, novels, the e-mails you sent to friends, loved ones or customers as well as the scribbling you make on rough paper. You may not have realized this but it is good to know that you can claim copyright over all of these and that copyright is the most common and proliferated form of intellectual property. Not all of these copyrighted materials will have any commercial value but before you stumble on something that does, it is good to have some basic understanding of this concept known as copyright.
