cast viewers was greater in New York City than it might have been in other metropolitan areas, as household cable penetration is only about 50 percent, significantly less than the nationwide average of 70 percent.)
To speed the restoration of broadcast service, the Federal Communications Commission gave stations temporary authority to locate replacement transmitters at any reasonable site, provided they would not cause interference with other stations’ activities. Shortly after the World Trade Center buildings collapsed, a number of broadcasters set up transmitters at a tower in Alpine, New Jersey. Since then, six networks have relocated transmitters to the Empire State Building, and two have remained at the Alpine site. Broadcasters do not consider this pair of sites adequate, however, for the long term: the Empire State Building does not have enough physical or electrical capacity for all of the broadcasters, and the Alpine tower, by virtue of its relatively modest height and remote location, does not serve as sizable a market as the World Trade Center site did. Efforts are now under way to select one or more permanent transmitter sites that are more suitable.
