Wozniak's refined engineering skills, coupled with Jobs's bold marketing abilities, led to a revolutionary and affordable product--as well as a successful company.

Thomas Edison's electric pen, an ancestor of both the mimeograph and the tattoo needle, was a successful product in the mid-1870s.

Many businesses found document duplication an attractive possibility.
