Random and Raster: Display Technologies and the Development of Videogames

Videogame developers have utilized many types of display technology, from oscilloscopes to Teletypes to high-definition LCD displays. Two significant early display technologies, raster scan and random scan CRTs, played a significant part in the history and evolution of videogames. A study of these technologies shows how the choice of one or the other, and the need to port games between the two, influenced game design and prompted developers to innovate.
