nowadays, most people can search for what they want through the Internet. The Internet has become powerful because it allows people to share or copy music, pictures, movies, software and different formats of documents. We know the Internet allows sharing of all kinds of information but that doesn’t mean it should be unrestricted. Through the Internet, people can find many materials and download them as references or for general interest, and some of these files are cheap or even free. Therefore, music downloading has become a popular way for people to get audio files. As downloading becomes a prevailing way to share information, the government decides to develop copyright laws to limit people. It can protect a creator’s rights and prevent other people from stealing original products.
