I believe those aren't all ISP subscribers, though, but also people who are still paying for the service via another ISP, because they don't realize AOL made it free. They used to charge something like $25/mo as an ISP, or $10/mo if you had your own ISP and just wanted to use the AOL client for email/AOL-keywords/whatever. Eventually they made that free, but not automatically--- you have to go click on something to request to be switched over to the (identical, except for support) free account, and many old AOL users either haven't noticed or haven't gotten around to it, or don't believe it. I switched my parents over about two years ago, because until then, they/I weren't actually sure they'd get to keep their email address if they dropped the paid account (as of about 4 years ago, you can).
