My timeline. Early 80s. Typing in BASIC programs from monthly magazines and saving them on magnetic tape (standard cassettes, short ones because you don't want to go to the end of a C90 even with fast forward). Late 80s. Floppy disks. Early 90s. Mostly floppy disks (eg Slackware Linux!) and some CDs but I had Internet at university since January 1st 1990 so I had Usenet and FTP there. Not at home and no portable computer. Mid 90s. DVDs, but they were mostly to backup data, music and movies. Then Internet at work -> CDs -> my computer. Then Internet at home and we got out of scope for OP's question.
