Back in the 1980s and early ‘90s, the hard drives on our computers at the radio station where I worked were cassette tapes that we erased and re-programmed several times a times a day (every six hours) for on air play to engage reel to reel tapes and carts (similar to 8 track tapes) to play music and commercials.
Imagine if you could go back in show up with a thumb drive and say this holds 64G of data; they’d first look at you like you were crazy then call you bonkers because they wouldn’t know how to access the data because USb hadnt been invented yet...lol
