Welcome to the old long distance billing model. Most of the capacity crunch was during daytime business hours so the cost was much higher during those times and it made sense from a network and a business standpoint.
The problem now is that the delineation between "peak" and "offpeak" in the Internet world has absolutely nothing to do with network usage and everything to do with how hot ISPs can turn up the pot before the consumer frog jumps out.
