This document provides an overview of the changes in media production and distribution that led to the development of Creative Commons (CC) licensing. It discusses:
1) A brief history of copyright and its purpose of incentivizing creation by allowing creators control over duplication of their works.
2) Four major technological revolutions - printing press, photography/film, radio/TV, and the internet - that made mass distribution of media possible and challenged existing copyright models.
3) How digitalization and the internet in particular allowed anyone to distribute media globally, raising issues around copyright that CC licensing was designed to address by providing options for sharing and reuse with attribution.
