Web Desk: The first commercial typewriter was manufactured in 1874, this was designed by Christopher Sholes in which he used the ‘QWERTY’ keyboard.
The manual typewriter was arranged in an alphabetic order, but the mechanical character arms got tangled up due to fast typing.
In his original prototype, Sholes had a problem with the bars colliding with each other and jamming, so he arranged the keys with the most common letters in hard to spots, to slow typist down and try to avoid this problem.
He randomly positioned to slow down typing and prevent key jams.
Later, the QWERTY keyboards were made so one could type using keys from the top row of the keyboard. This random arrangement became standard.
