As I recall, "broadband" originally meant bit rate greater than the baud rate. V.32 qualified under that definition. I think it used a QAM modulation on a 2.4kHz baseband carrier - details are somewhat hazy now. Came in late 80s. I was certainly using the internet from home from around 1993, and I think that must have been with V.32 or V.32bis because 56K modems didn't really arrive till the late 90s. Not sure what broadband means these days, other than vaguely high bandwidth.
But I accept that this is special pleading, and binary has a point. 20+ years is nearer the mark. Too long, anyway. Through ADSL and now FTTC, BT's wire (both copper and some aluminium, OR have admitted to me) has caused nothing but trouble which armies of OR engineers have failed to fix. I can't wait to be rid of it all for good.
But I/we digress. Sorry.
No, digression is great! I remember looking longingly at 56K modems in the late 90's, whilst using a 28.8 or 33.6 kbit/s internal one that came with the PC. Given the costs and inconvenience of dial-up, it was hard to justify an upgrade.
Regarding those earlier times, I recall a family member who keenly took to email but didn't really get their head around the web until the arrival of (ADSL) broadband. The advent of 'always-on' internet connections in the home made all the difference.
I also remember noting on many occasions how the North American software design just assumed that local calls (to ISP's POPs/ access numbers) were free/inclusive, totally failing to take account of Europe (and elsewhere) where such calls were charged per minute... meaning every second online counted!
Anyway I am off to watch something on my HD telly, though I still haven't got my head around the fuss regarding
'high definition television', given that it's been around since 1936...
