Written as a personal favor for a friend, "The Fun They Had" became more popular than he expected. It is about computerizedhome schooling, and what children miss out on by not being in school together. It is the most anthologized of all Asimov's stories and has appeared in many publications outside of the science fiction genre.
Set in the year 2155, when children learn individually at home using a mechanical teacher, the story tells of eleven-year-old Margie Jones, whose friend Tommy finds a real book. The book tells about a time when children learned altogether in a group in a place called a school. They discuss what it must have been like to be together with a real person as a teacher, and 'the fun they had'.
