Copyright law protects various types of creative works including books, music, art, films, and software. It gives copyright holders the exclusive right to distribute and profit from their work. However, software piracy, which is the illegal copying and distribution of software without a license, remains a major problem exacerbated by the internet and CD burning technology. While copyright holders use methods like serial numbers, dongles, and regional coding to prevent piracy, these protections are often broken, leaving copyright law as the main deterrent against software piracy.
