Thats the point though- this would theoretically be perpetrated by the cable providers, and they attempt to recoup all of their lost tv revenue via increased internet costs.
Comcast already did it without usage based billing- I have internet only and they jacked it up to $70/month from $40, if I bought a internet + tv package it'd be $75.
Canadian cable provider Shaw posted their new rate plans for internet only (were to start in November).. same thing, there was basically no difference between internet only and internet+cable in cost. I said "see ya!" and switched to a dsl provider at a substantial discount to the new internet rates.
You have to go deep into the Shaw cable website to find the real internet package pricing -- on their main page they proudly announced "29.95" for "Broadband 50". Going into the details:
INTRODUCTORY OFFER
For 6 Months
$29.95/mo
Bundled Price
$59.00/mo
Standalone Price
$74.90/mo
There are some older packages available, not well advertised, and probably to be deleted in the future. Still, basic internet (when you find it on their site) is $42.50 a month with TV, and $52.50 a month without. That's at least $10 more than basic DSL service around here.
