Time Warner installed cable when the homes were being built. Then about 10 years ago AT&T went through and installed their "fiber" (their words, not mine), and tore up everyone's lawn in the process. This last year Google came in... and just made an enormous mess[1]... but the good news is they did lay pipe that other services can run cables through.
[1] I've commended on this recently in other posts -- Google isn't supervising the contractors they hire in Austin and the work is getting done shoddy... and Google hasn't been doing much of anything to remedy the situation.
