For what it's worth, MySpace prior to officially being a social media site was created in '96 and officially launched as a internet network drive around 1999 cant remember the exact date, then was later sold to Murdoch and evolved more into a social media site later on but was already unofficially used as one. People shared music, short movies, porn. It didn't scale well as there was no de-duplication, files were stored in an EBCDIC database on a couple HP Surestore's which I and others upgraded a few times from 9TB to 18TB comprised of 4 and 9 GB drives, then eventually 18 GB drives.
