Console Wars: Sega, Nintendo, and the Battle That Defined a Generation is a 2014 non-fiction novel written by Blake J. Harris. It follows businessman Tom Kalinske in his venture as CEO of video game company Sega of America from 1990 to 1996, and details the history of the fierce business competition between Sega and Nintendo throughout the 1990s as well as the internal conflicts that took place between Sega of America and its Japanese parent company, Sega Enterprise. Harris wrote the book in the style of a novel by compiling several interviews with people who were involved with the events, using the information gathered to create a dramatic interpretation of the events. A documentary of the book directed by Harris and Jonah Tulis was released on CBS All Access on September 23, 2020. A miniseries adaptation is in development with Seth Rogen and Evan Goldberg executive producing with Jordan Vogt-Roberts directing.
