AOL demographics (Score 3, Interesting)

Does anybody know of any studies on the demographics of AOL customers? My hunch, from those I know who use it, togeher with AOL advertising (I'm in the UK), would be that it tends to be:

(a) Net newbies who then keep renewing their service
(b) Older folks who like a bit of hand-holding

This is not meant to be derogatory --- I'm simply curious as to who these millions are and why they stick with a service that is slow, cumbersome and expensive.
