I have a small laptop that tunes TV. We use it during stormy periods because our electricity usually goes out.
I think I could do without broadcast stations entirely, and certainly most cable stations ~ like who needs 999 channels when you can have millions.
But I think your question really was, where's this fiber optic that I can sign up with. I've got 5 of them running through my front yard. You may have one too.

Forgot you could get a tuner for the computer - that might be something to do just for a few sports now and then, but I do DSL for my internet and I was more curious on where to find additional content.
