Eventually communication reached an electronic state, and the telegraph was invented. Harrison Dyar, who sent electrical sparks through chemically treated paper tape to burn dots and dashes, invented the first telegraph in the USA. The telegraph was the first piece of equipment that allowed users to send electronic messages. A more developed version came from Samuel Morse, whose telegraph printed code on tape and was operated using a keypad and an earpiece. The pattern of communication soon became known as Morse code.
Typewriter
The next step in the development of the electric typewriter came in 1910, when Charles and Howard Krum filed a patent for the first practical teletypewriter. The Krums' machine, named the Morkrum Printing Telegraph, used a typewheel rather than individual typebars. This machine was used for the first commercial teletypewriter system on Postal Telegraph Company lines between Boston and New York City in 1910.
