On the coasts, many areas are still under legacy (and even new) franchise agreements. The New York City franchise map is a good example that is readily available - provider A is allowed to operate on one side of the street, on the other side only provider B can offer service. Customers get whichever ISP is assigned to their area by the bureaucrats (who get donations from the ISPs). The ISPs are free to suck, because there's no competition.
There was some hoopla around here a couple of years ago with people saying "franchise monopolies are now illegal". Not quite. The rule from the Obama administration was "before issuing a *new* franchise monopoly, a city must hold a meeting."
In many parts of Texas, we don't have the franchise (mandated monopoly) system. Instead, new providers are allowed to enter an area and offer better service. These are called "overbuilders" because they build new infrastructure, using modern technology, right on top of the incumbent's legacy network. Many provide "cable" TV and internet.
The last 10 years or so have been a very important time for overbuilders because previously, the incumbent had a huge advantage in that they already had the infrastructure in place. It's major expense for an overbuilder to replicate all the wiring that the legacy provider already has. The incumbent doesn't have that current cost. In some areas, the phone company was providing DSL service using wiring they laid 60 years ago.
Now that we're going to high-speed fiber, the incumbent no longer has the same advantage. Their decades-old copper infrastructure isn't an overwhelming advantage any more. Overbuilders come in and lay fiber, often with short lengths of high-quality, high-capacity coax for the last few hundred feet. In some parts of Austin there are four to six providers to choose from. Even in some very small towns there are two cable TV companies, competing to have the best, most reliable, and fastest network. If they one doesn't do a good job, customers don't choose them, and the company doesn't make money. Companies like to make money, of course, so they don't suck, not to the extent that they suck in guaranteed monopoly areas (government franchises). The lead engineer for my city of 150,000 gave me his cell phone number, telling me to call him directly if I have any problems and customer service doesn't take care of it properly.
> list of reasons to move to Texas will gain another entry.
We'd love to have you! Please bring that list with you. A lot of Californians move out here and I ask why they came. They came, perhaps, because we have good jobs and a low cost of living. A programmer II can afford a 2,600 square foot house here. Within a week they start telling me about things we should change in Texas, to be more like California. We should have California-style policies, they say, and they don't hear me when I point out those policies drive up costs and increase unemployment. Not that they are necessarily BAD policies. Maybe the benefits outweigh the costs, in some people's opinion. Fine. But if you want to do things the California way, and get the results California gets, it's easy to just stay in California. No need to come to Texas and try to turn it into California.
