...the cable system in Walworth, Wisconsin, had the affiliates from three different markets -- Milwaukee, Chicago and Rockford IL -- when I lived there in '98-'99. I assume they were all grandfathered in from the '70s or '80s. Curiously, while Rockford was clearly the closest market, Walworth County is officially part of the Milwaukee ADI, and the head-end of the system's signal was actually in McHenry County, Illinois, part of the Chicago ADI...
To piggyback on your comments, the Charter system serving Beloit and Janesville (Rock County, Wisconsin) have always carried the Madison (in-market) and Rockford (out-of-market, but geographically closer) network affiliates, and plus they used to offer Milwaukee's WVTV back when it was marketed as a "regional superstation".

In Rockford, The CW and MyNetworkTV are offered on digital subs (WREX 13.2 and WTVO 17.2 respectively), as well as AccuWeather on WIFR 23.2. Other than that, all of the full-powered Madison and Rockford all are offered via cable in that area; TBN, who has over-the-air stations serving parts of the Madison market, is carried by the Charter system (along with three of its four subchannels) but from TBN's national feed.
