You’d be wrong. That dubious honor goes to Comcast (aka Comcrap), which of course is in talks to acquire Time Warner Cable.

BTW – I thought we were mainly talking about ISPs. I’ve never had a cable account in my life. What little TV I watch is either over-the-air HD (actually rebroadcast via my building’s cable right now, but free) or streaming via Netflix, or in some cases, downloaded via BitTorrent.
