Comparing WWOR to the Spanish stations in the NY and Philadelphia markets in their 'lack of service' to New Jersey is ridiculous. Back in the days when they were just HSN and public domain movie pipelines the case might have been made, but these days? The market is there, and their newscasts definitely serve the public interest. At least they're making some kind of effort even if they're mostly airing national content most of the time.
WWOR though? The only interest they seem to serve is to push a service nationally which can best be described as 'ION in primetime' these days, a bunch of mediocre syndicated content, and a whole load of infomercials, and TMZ-ing the news has proven to be a dud, as Tribune's "EyeOpener" format has proven on their dud CW affiliates. Clearly they have not been serving the public interest and their license deserves a challenge. But WXTV, WNJU, WUVP and WWSI? It would be an embarrassment to challenge their licenses.
It would be like the FCC challenging the license of the CW affiliate in the Green Bay area just because they don't air only public affairs programming only pertaining to its 'city' of license, Suring, which has nothing going on about 362 days of the year and would be just the Kiwanis Club blabbering on about a fish fry every single week it was on; you look at the market situation, not the strictest interpretation of the law, and clearly WWOR isn't serving the market well while WXTV and WNJU have done what they've needed.
