Re: it's application was completely different to floppy disks
Okay, I get your point.
Nonetheless, floppies disappeared in software boxes and were replaced by CDs due to the practical side of Windows on 1 CD instead of 48 floppies.
And the industry liked the idea of locking content on CD, which they did more or less successfully, and which was all but impossible on floppy disks.
USB keys, ultimately, replaced the floppy in everyday data transfers, I agree. But the CD set the floppy disk on the path to oblivion.
