A postliterate society is a hypothetical society in which multimedia technology has advanced to the point where literacy, the ability to read or write, is no longer necessary or common.
The term appears as early as 1962 in Marshall McLuhan’s The Gutenberg Galaxy. Many science-fiction societies are postliterate, as in Ray Bradbury’s Fahrenheit 451, Dan Simmons’ novel Ilium, and Gary Shteyngart’s Super Sad True Love Story.
