The "band" in broadband stands for bandwidth.
Once upon a time, when I was only 35, there was only POTS (plain old
telephone service) to transmit the internet (and its precursors like
Bitnet) very slowly (I remember 11 characters per second). Although POTS
got faster until it was good enough for reading email in almost-real time:
256Kb/second as I recall.
It wasn't until new technologies came along to transmit information much
more quickly through not-so-plain phone wires, cable and then satellite.
This made it possible to read without cursing our current graphics-heavy
web sites. (And to download stuff quickly, instead of overnight.)
In comparison to the narrow bandwith of POTS (narrowband), the new
technologies collectively became known as "broadband".
Want to know more? I'm "sure" Wikipedia has it for you.
