Well, I for one use wireless internet from AT&T and Verizon instead of using comcast.

They both provide internet. I chose wireless because the speeds were sufficient but they're portable and I travel a lot.

T-Mobile is now offering free Netflix.

AT&T was (or is) offering free Hulu.

Just like landlines are a thing of the past, once wireless speeds catch up, I think we'll see a similar shift.

But certainly, a better comparison is Comcast to other cable/dsl providers. And they do compete... Google Fiber and Comcast, for instance. Google offers free fiber internet (low speeds). Gets people hooked, and then its easy to upsell them.
