The term “word processor” is usually associated with software such as “Microsoft Word” or Google Docs, but its origin is way older than that. It originated not from digital technology but from working in offices with mechanical typewriter machines in the early 70s. The term “word processing” was first invented by a German sales engineer in the 1950s (translated from the German word “Textverarbeitung”). The term did not gain traction until a New Times article declared “word processor” as a business buzzword in the 70s and referred to IBM electronic typewriters.
