The beacon is usually on the roof of a tall building in a central business district, but some are attached to towers. The beacons are most commonly owned by financial services companies and television stations and are part of advertising and public relations programs. They provide a very basic forecast for the general public and not as an aid to navigation.
In addition to displaying weather forecasts, some weather beacons have been used to signal victory or defeat for a professional sports home team.
The first attempt to create a weather beacon as a form of advertising was from Douglas Leigh, who, in 1941, arranged a lighting scheme for the Empire State Building to display a weather forecast code with a decoder to be packaged with Coca-Cola bottles. The plan was never implemented because of the attack on Pearl Harbor later that year. Leigh resurrected his idea in Minneapolis in October 1949 with the Northwestern National Bank Weatherball.
Weather beacons were most popular during the 1950s and '60s.
