and has been translated into dozens of languages. He continued the theme in The Third Wave in 1980. While he describes the first and second waves as the agricultural and industrial revolutions, the "third wave," a phrase he coined, represents the current information, computer-based revolution. He forecast the spread of the Internet and email, interactive media, cable television, cloning, and other digital advancements. He claimed that one of the side effects of the digital age has been "information overload," another term he coined. In 1990, he wrote Powershift, also with the help of his wife, Heidi.

An often misattributed quote, however, is that of psychologist Herbert Gerjuoy: "Tomorrow's illiterate will not be the man who can't read; he will be the man who has not learned how to learn."

He explained during an interview that some visitors would become "truly disoriented and upset" by the strange environment, which he described as a reaction to culture shock. From that issue, he foresaw another problem for the future, when a culturally "new environment comes to you ... and comes to you rapidly." That kind of sudden cultural change within one's own country, which he felt many would not understand, would lead to a similar reaction, one of "future shock", which he wrote
