Weather media in the United States
The weather media in the United States includes coverage of weather and weather forecasting by farmers' almanacs, newspapers, radio, television stations, and the internet. Farmers' Almanacs have taken a stab at forecasting for the following year or so for around two centuries. At first, weather media included reporting on past events, with forecasting playing a role from the late 19th century onward. Weather-related information proliferated to near real-time after the invention of the telegraph. Radio and satellite broadcasts made weather-related communication ever quicker, with the World Wide Web making broadcasting and reporting nearly instantaneous. By the 1990s, sensationalism played a role in weather coverage.
==Farmers almanacs==
Farmers' Almanacs have published long-term forecasts for around 200 years. While almanac publishers have attributed an 80 to 85 percent accuracy rate to the publication’s annual forecasts, independent studies that retrospectively compare the weather with the predictions have not shown them more accurate than chance. Predictions for each edition are made as far as two years in advance. The ''Farmers’ Almanac'' publishers are highly secretive about the method used to make its predictions, only stating publicly that it is a "top secret mathematical and astronomical formula, that relies on sunspot activity, tidal action, planetary position and many other factors."
