It was not, however, the first piece of software which made the microcomputer useful. Credit for that should go to Electric Pencil (1976), the first word processor for microcomputers, released three years before VisiCalc (1979).
WordStar (1978) also came out before VisiCalc.
So, perhaps IoT is really missing its Electric Pencil?
