Comcast owns the rights to their "iGuide." Any other cable co that uses that guide actually pays Comcast royalty fees. As far as it not being updated since 2005, that's actually not true (don't get me wrong, it's still shitty). Updates come out, however it can take years for some places to see the updates (and some areas never see them) since they're rolled out on a market-by-market/headend-by-headend basis, and not all areas have the capability to run the new updates.
I will post pictures of my beloved FiOS guide later on
