Today is National Radio Day. The radio dates back to the 1800's but first  became popular in the 1920's with the first radio broadcasting station opened in 1922. Radios were used to broadcast news and world affairs. Eventually broadcasting companies went on to introduce entertainment shows with broadcast such as "The War of the Worlds".
