The metro area grew outward rather than upward, and it grew in waves. A subdivision built in the 1970s was cabled for what existed then; one built in the last decade was wired for fiber from the start.
Two things follow. What your neighbor two miles away can order may not be available at your address. And the provider who serves a new development often has no presence in the older one next to it.
IPTV removes that variable. The service runs over whatever broadband reaches you, so the question is only whether you have a connection rather than which franchise holds your street.
For households in the newer developments with good fiber, the choice is simply between keeping a package and replacing it.
The second local factor is weather. Gulf storms interrupt a rooftop dish, and the season when they are most frequent is also when a household is most likely to be indoors watching.
A broadband connection is not immune to a storm, but it fails for different reasons and recovers differently. Where a dish loses signal through rain fade, a wired connection generally keeps working until the power does.
The practical consequence is that moving within the metro area, which here can mean twenty miles without leaving the city, does not require renegotiating anything.
The same credentials work at the new address. No transfer request, no cancellation fee, no gap between disconnection and activation.
For the connection itself, the newer parts of the metro area are well served, and the limiting factor in most homes is the distance between the router and the television rather than the plan.
