Here is a brief video showing the Evolution/ history of the Typewriter.
The first commercial typewriters were introduced in 1874, but did not become common in offices until after the mid-1880s. The typewriter quickly became an indispensable tool for practically all writing other than personal handwritten correspondence. It was widely used by professional writers, in offices, and for business correspondence in private homes.

Typewriters were a standard fixture in most offices up to the 1980s. Thereafter, they began to be largely supplanted by computers. Nevertheless, typewriters remain common in some parts of the world, are required for a few specific applications, and are popular in certain subcultures. In many Indian cities and towns, typewriters are still used, especially in roadside and legal offices due to a lack of continuous, reliable electricity. The QWERTY keyboard continues to be the standard used in computers too.
