I have never seen a commercial for home internet service that is explicitly unlimited it's usually:
Blazing* Fast** High-Speed*** Internet**** Up to***** 50****** megs******* for only******** $69.99 per month*********
* Our lawyers advise us to tell you that we are not liable any house fires that may or may not be related to your internet equipment.
** When compared to dial up internet from 20 years ago
*** Only available during off-peak hours
**** Until we decide to deny access to websites that don't pay us for the privilege of being carried to our customers
***** But never actually anywhere near....
****** Random number picked out of a hat, you'll never actually get this
******* Bits? Bytes? Who cares! (Personal story: I asked the Comcast salesmen if he meant megabits or megabytes when he said "50 megs" and he had no idea...)
******** Introductory rate for new customers only. We will double the rates in 3 months after joining
********* Plus taxes, fees, extra charges, and tribute payments
