This just in:

"RoadRunner is a service of AOL Time Warner, but AFAIK, it's only an ISP
that has cable companies ("MSO's") as affiliates.

Road Runner isn't a cable television provider, itself."

I believe, however that Andy is right. I think my confusion is that COX
bought the AT&T @home groups, which includes roadrunner. usually AT&T is
the one buying.

Thanks for the info.
