Piracy is the illegal use of copyrighted material. Pirates usually target music, movies, or software, although visual designs are also pirated. Making counterfeit products and re-branding or modifying products are also acts of piracy. Another crime is the sale of demo notional materials, an example being the DVDs used for Academy Award screenings. Unlike physical theft, most people do not feel guilty about downloading pirated music or movies. Music and film industries believe that 25 billion dollars per year is lost in the United States alone by people pirating content.
