This could mean some bad news for WMGM-TV 40 (NBC).
Right now, WMGM-TV's primary competition in local advertising is Comcast. The local Shore businesses can choose to buy visual air time on Comcast or WMGM.
Comcast already played hardball with them when they dropped CH.40 off the analog in Vineland, Cumberland County. From a cable spot of Ch.21 to Ch.99 to digital-only cable Ch.247 or something there, it still tries to service that county with Vineland news. Given Comcast's monopolistic nature, they could apply pressure so the affiliation is ceased, so that Ch.10 is the only NBC (boosting WCAU's resale value a little) and more that nobody will choose to advertise on WMGM, so that Comcast reaps the entire advertising market, like they do in Ocean county and other counties underserved by being outside the immediate metros of NY or Philly.
Verizon currently doesn't service Atlantic and Cape May Counties, and DirecTV and Dish are without the local pro Philly sports (via CSN-Philly).
