IF the merger had gone through in our area TWC would of become Comcast ,there would of been no competition. TWC is the only cable broadband internet in town and we have no bandwith caps. So bandwith caps would of been a real problem in my house hold with a 14 year old boy who is constantly on his computer , playstation 2 and every other wireless device in the house.Charter I believe is 400gb a month.
Comcast does not have caps in every market it serves, here in Michigan we have none ( but they keep trying ), the main reason is in a lot of Comcast areas here they have competition in Uverse, Charter , Bright House and WOW and soon Century Link.
I have noticed that in most of the areas that have caps there is no competition with Comcast.
