The DMCA (Digital Millennium Copyright Act) is a copyright law in the United States that addresses copyright infringement on the internet. It provides a framework for copyright owners to protect their works and take action against those who violate their rights online. The DMCA includes provisions for notice and takedown procedures, which allow copyright holders to request the removal of infringing content from websites and online platforms. It also includes provisions for safe harbor, which protect internet service providers from liability for the actions of their users. The DMCA has been instrumental in combating online piracy and protecting the rights of copyright owners in the digital age.
