1. Typewriters gave us a way to communicate when modern technology wasn't around. That was the modern technology for the people.
2. Another use for the typewriter was how it would print ink on paper and help make one look very professional in the day. It enabled many people to get done with books, plays, reports, and so on.
Fun fact: Typewriters were invented around 1869 but Herny Mill was the very first person to think of the idea of a "typewriter" within 1714.
