Back in those days, people weren't storing vast amounts of high def video. Video they had was encoded at some crappy bit-rate, and their music was all 128kbit MP3 - or still on physical CD. Or, if it was digital, before MP3 was stored in 11khz or 22khz 8 bit at best. Downloading? as mentioned above 56k modems can't download things very fast - rather than downloading several gb per hour, you'd be lucky to get a couple of hundred meg in 24 hrs.
People weren't taking photos with 10+ megapixel DSLR cameras, and storing them all in RAW format on their machine.
Using a 56k modem was not unbearable, but man... it left you dieing for more speed. Seeing high-speed internet at my university was incredible.
People weren't doing most of these things because they hadn't been invented yet. HD video didn't exist on computers yet since the resolutions of the monitors was not available. Again, back in the 90's a 17" monitor was considered massive! I remember getting one in 2001 and thinking that I could die a happy man (though I was barely 20 then).
And 10 megapixels!!??!?!? That was such crazy talk no one ever muttered the words.
