Goodbye to typewriters"

India is well known for its legions of computer programmers, but the country also has another face as the last bastion of the typewriter. Manual typewriters stayed popular in India long after developed nations had entirely switched to the keyboard and mouse.

As recently as the 1990s, the Mumbai plant of a company named Godrej and Boyce was turning out 50,000 typewriters a year. They were popular in a nation where reliable electricity supplies - essential for computers - are still by no means guaranteed.
