When will Xfinity come to our area?

We would like to use Xfinity, however they're not in our part of Kentucky, Ashland. We are a few minutes' drive from both OH and WV, and in those few minutes, Xfinity can be used. Why is KY so scarce of when it comes to Xfinity? We have Kinetic advertising and door knocking HEAVILY in our area, but they've not even installed any lines for potential customers. With Xfinity simply stating "We're not in your area yet", we have zero idea when - or perhaps if! - Xfinity will be an internet provider where we are.
