Content ID is a digital fingerprinting system developed by Google which is used to easily identify and manage copyrighted content on YouTube. Videos uploaded to YouTube are compared against audio and video files registered with Content ID by content owners, looking for any matches. Content owners have the choice to have matching content blocked or to monetize it. The system began to be implemented around 2007. By 2016, it had cost $60 million to develop and led to around $2 billion in payments to copyright holders.^[1] By 2018, Google had invested at least $100 million into the system.^[2]
