When would you say that floppies started to be in widespread use?
My first encounters were ( if memory has not been corrupted ) on a Data General microNova early 1970's
I just learnt this for the first time
In 1967, at an IBM facility in San Jose (CA), work began on a drive that led to the world's first floppy disk and disk drive. It was introduced into the market in an 8-inch (20 cm) format in 1972.
