I had a feeling this may happen. As part of Comcast's mega-deal to swallow up Time Warner Cable, they're going to have to divest themselves of some subscribers to make the deal go through. They've apparently made a deal with Charter to have them purchase said subscribers, and that includes Wisconsin -- according to the Associated Press and FOX 11.
I don't know much about Charter myself, but they do service many rural communities here in Northeast Wisconsin. Comcast, to me, seemed to be a little more technologically progressive in their offerings, and Charter used to have a certain reputation -- at least around here -- of being slow to roll out new services like additional HD channels. How this will affect Time Warner subs, their local workforce and the services offered in this area, is yet to be seen.
I was really holding out hope for Time Warner's dramatically-increased residential Internet speeds, which they rolled out in Texas earlier this year. I hope Charter will be able to leverage the pretty robust network TWC has built to continue offering good service.
