I pay for service of a given speed NOW but do not get that speed during peak times of the day. The amount of data being sent over the network is increasing significantly and the timing of that use is not even. I pay for a given service but growth in demand doesn't permit me the service I paid for at those times.
And again, you insist on pretending that there is no connection between data use and bandwidth -- how is that even possible? You then said it cost less to send data during off-peak and I pointed out that you couldn't be more wrong.
If many users with low speed service stream audio 24/7 it doesn't much matter that the per user data rate is relatively small the aggregate effect will be to kill the network. What part of this do you not understand?

If isp's are paying for bandwidth, then they are paying for it whether it's used or not at all points in the day for the month. The only thing that makes the cost go up is the peak bandwidth. Note that they can throttle to keep this at the level they want. Data at off peak costs not less, but almost nothing, because it does not affect the cost for the ISP.
Another thing to note - I am going on the conclusion that isp's pay for bandwidth based on a certain type of model, something like a 95/5 (where the 5% outlier usage is discarded). If anyone has more information on this please let me know, this stuff doesn't seem to be easy to find details on.
So I'll use an example. Say I move into a neighborhood and get internet service, 50/5 for example. The ISP had a cost of X before I move in. Now I begin to use the service, but only at 12am to 6am. So not peak times. Say for some reason I max my connection during these times for the month. A quick calc gives me over 4Tb of usage. But what is the increased cost for the ISP? Very little if they are paying for a peak bandwidth at all times for the month. My connection will not approach the bandwidth they are paying for, so they don't pay more that way. The equipment runs regardless of whether I use it, so no more expense that way. It may cost a bit more in electricity to run the routers....
So if there is almost no increase in cost for that extreme example, why bill for total usage?
What are we billing for? Bandwidth, because its the only variable that directly increases cost. And that really is just a way to bill for a larger expense - the infrastructure. That's why the idea that someone who only emails has almost no cost to the ISP is wrong. You are paying for the service to be available, whether you use it or not.
TV is similar. They don't care how much you watch TV, you just pay for it to be available.
The infrastructure detail is important. If that wasn't a large driver of cost then we wouldn't see large areas without decent service.
Sorry if this looks bad, typed this on my phone.
