This document provides an overview of the evolution of new media video formats from analog to digital. It discusses early recorded audio and video formats from cylinders and discs to tapes and files. It then covers the development of digital video formats including DVD, Blu-ray, and file-based formats for downloading and streaming video over networks. The document also summarizes key breakthroughs in digital video encoding, camcorders, and editing from analog linear to digital non-linear systems.
