The Moon Is a Harsh Mistress [wikipedia.org] by Robert A. Heinlein was published in 1966:
The book popularized the acronym TANSTAAFL ("There Ain't No Such Thing As A Free Lunch"), and helped popularize the constructed language Loglan, which is used in the story for precise human-computer interaction. The Oxford Dictionary of Quotations credits this novel with the first printed appearance of the phrase "There's no free lunch", although the phrase and its abbreviation considerably predate the novel.
The virtual assistant Mycroft [wikipedia.org] is named after a computer system from the novel.
