Copyright is a bundle of exclusive rights granted to creators of original works to prevent unauthorized copying. While creators in ancient times did not worry about copying, the invention of the printing press led to concerns about unauthorized copying depriving authors of rewards for their work. Later, other categories of works like films and sound recordings were included under copyright.
The objectives of copyright law are to encourage creation of new works by rewarding creators with limited exclusive rights, and to prevent unauthorized exploitation of others' works. Copyright automatically exists in original literary, artistic, dramatic or musical works when fixed in a tangible form. Though facts are not copyrightable, compilations of facts can be if there is a minimal level of creativity in the selection or arrangement.
