Can somebody help me quickly find out roughly how many floppy diskettes were sold world wide in 2005?

Answer 1

Since floppy disks went out with the dodo bird years ago, only very poor third world countries still using pre-pentium cpus and disk drives would sell those things, and finding out how many would be virtually impossible.

Answer 2

Probably not very many, about 1.5 million. You'll need to contact each store who sells floppys and ask them. I'd say it will take you about 4 years to collect the information.
