エンパイア・ステート・ビルディング
The placement of the stations in the Empire State Building became a major issue with the construction of the World Trade Center's Twin Towers in the late 1960s, and early 1970s. The greater height of the Twin Towers would reflect radio waves broadcast from the Empire State Building, eventually resulting in some broadcasters relocating to the newer towers instead of suing the developer, the Port Authority of New York and New Jersey. Even though the nine stations who were broadcasting from the Empire State Building were leasing their broadcast space until 1984, most of these stations moved to the World Trade Center as soon as it was completed in 1971. The broadcasters obtained a court order stipulating that the Port Authority had to build a mast and transmission equipment in the North Tower, as well as pay the broadcasters' leases in the Empire State Building until 1984. Only a few broadcasters renewed their leases in the Empire State Building.
