In an article published in the North American Review in June 1878 Thomas Edison described future uses for his phonograph, which he had invented on August 12, 1877:
- Letter writing and all kinds of dictation without the aid of a stenographer.
- Phonographic books, which will speak to blind people without effort on their part.
- The teaching of elocution.
- Reproduction of music.
- The "Family Record"--a registry of sayings, reminiscences, etc., by members of a family in their own voices, and of the last words of dying persons.
- Music-boxes and toys.
- Clocks that should announce in articulate speech the time for going home, going to meals, etc.
- The preservation of languages by exact reproduction of the manner of pronouncing.
- Educational purposes; such as preserving the explanations made by a teacher, so that the pupil can refer to them at any moment, and spelling or other lessons placed upon the phonograph for convenience in committing to memory.
- Connection with the telephone, so as to make that instrument an auxiliary in the transmission of permanent and invaluable records, instead of being the recipient of momentary and fleeting communication."
