About five per cent of adults still use dialup, AOL or otherwise. Let’s assume that rounds out to about about 10 million people. That’s a lot! That’s a whole 56k Belgium. Or narrow-band New York City.
Dial-up is still cheaper that broadband, but not by much. The reasons for living with 56k run like this: You don’t want to, or can’t, pay for broadband; you live in a rural area without broadband; or, most commonly, you have never even heard of “broadband.”
