Why is "Alaska Communications System" trending?

Wikipedia Overview

The Alaska Communication System (ACS), also known as the Washington-Alaska Military Cable and Telegraph System (WAMCATS), was a system of cables and telegraph lines authorized by the U.S. Congress in 1900 and constructed by the U.S. Army Signal Corps. The communications lines were to serve both military and civilian needs in the territory of Alaska. By 1904, ACS comprised some 2,100 miles (3,400 km) of undersea cable, over 1,400 miles (2,300 km) of land lines, and a wireless segment across at least 107 miles (172 km). On 15 May 1936 WAMCATS was renamed the U.S. Army Alaska Communication System. The Alaska Communication System remained under the control of the Army Signal Corps until 1962 when it was taken over by the U.S. Air Force. The ACS handled the radioteletype, radio telephone, 500 kHz ship-to-shore frequencies, collected communications intelligence, and other services for more than half a century in Alaska.
