At the least the networks also own stations in the next market over, in Philadelphia. In the case of ABC, if things really went dire, they could get assistance from either their sister station in Philadelphia, WPVI 6ABC or their corporate cousins at ESPN in either their Bristol, CT studios or their South Street Seaport studios in Lower Manhattan, which was unaffected by the blackout. The blackout affected Fox News, since they were on Sixth Avenue but not WNYW, which is on East 67th Street. NBC also has studios in Wall Street for CNBC, if they couldn't make it to New Jersey. And if CBS ever needed some backup, Philadelphia sister station KYW 3 could pinch-hit. Fox could also rely on help from WTXF 29.
