In the US, two infrastructures evolved into internet infrastructure, one was the phone service (pretty much AT&T's long distance network and Ma Bell's local infrastructure). The other was the local Cable Companies, Cox, Bright house, Comcast et. al. So in most locations you have one of two choices, go with DSL and the phone company or Cable which in many areas is Comcast. AT&T just installed fiber here in the Florida Key's so alternatives are starting to pop up in more remote locations in the US, but it's still pretty much a go with the local phone company or local cable company monopoly decision.
