The document discusses the history of new technologies and how they are initially seen as novel but eventually become mainstream and standardized. It makes three key points: 1. New technologies are often built upon older technologies and are initially not seen as completely new, but as improvements on the old. Early cinema combined existing technologies like still photos and magic lanterns. 2. As technologies develop new social uses and become subject to legal regulations and economic forces, power structures seek to control the technologies and their industries, as happened with the institutionalization and Hollywood domination of cinema. 3. Technologies only become truly mainstream and taken-for-granted after going through periods of technical invention, cultural innovation, legal regulation, economic distribution
