A typewriter is a mechanical or electromechanical device with a set of keys that, when pressed, cause characters to be printed on a medium, usually paper.
From their invention before 1870 through much of the 20th century, typewriters were indispensable tools for many professional writers and in business offices.________
By the end of the 1980s, word processors and personal computers had largely replaced the tasks previously accomplished with typewriters in the western world.
Typewriters, however, remain in use in various areas of the world.________
Notable typewriter manufacturer companies have included E. Remington and Sons, IBM, Imperial Typewriters, Oliver Typewriter Company, Olivetti, Royal Typewriter Company, Smith Corona, and Underwood Typewriter Company.________
