Whereas privacy law allows people to limit public dissemination of private information about themselves, copyright allows authors to control how their creative expression is copied, distributed, and performed. Copyright protects books, musical compositions, videos, newspaper articles, recordings, software, TV programs, advertisements, podcasts, email, and other original expression from unauthorized copying and performance. Copyright law punishes those who infringe the rights of authors to control the reproduction, adaptation, distribution, display, and performance of their original works.
