Broadband really started with @Home
I seem to remember that cable modems were the first mass-market broadband. ISDN was a joke. Once @Home started taking off, DSL expansion and all the rest followed.
I found a CableLabs/DOCSIS history page here:
I actually can't remember if @HOME started offering service before DOCSIS 1.0, I think so.
Cable Broadband started with @Home and died with @Home, since Concast took over they have done nothing but limit its potential with invisible caps and now the 250GB joke of a cap. I am just glad Verizon has upgraded me to FiOS and now I have a connection that can smoke anything Cable can offer now and in the future and all with no caps, they are also standing up to the BS fishing lawsuits instead of just giving in.
