AT&T Alascom has extensive telecommunications infrastructure in Alaska, including three satellites, undersea and terrestrial cables containing optical fiber, and numerous earth stations.
Unlike most of the United States, AT&T had no role in Alaskan telecommunications as a local or long distance telephone provider until the purchase of Alascom in 1995.
Alascom and General Communications, Inc. have been the two primary competitors for long-distance telephone service in Alaska since GCI's founding in 1979.
The company began in 1900 when the U.S. Congress authorized the U.S. Army Signal Corps to create the Washington-Alaska Military Cable and Telegraph System, or WAMCATS.
Alascom greatly built up the telecommunications infrastructure in the state during this time, due to RCA's major involvement in communications satellites.
