Historical News Database: "Broadcast Radio"

New York Times (October 14, 1921):

This article discusses that the earlier development of the radio was referred to as the telegraph-"the first instantaneous system of information movement." It goes on to saying that during the war, "radio broadcast" was exclusively used to communicate with the navy while over seas.They used Morse code in order to communicate between ships. The article continues to explain that, "Navy wireless facilities may be utilized to disseminate news of the armament conference, of the recommendations of some high Administration officials..."

Chicago Tribune (February 10, 1924):

This article refers to the aid in which radio stations provide to local cities that are under severe weather warnings. The article was about a severe weather emergency in Chicago, IL. It reads, "Steps for thorough preparedness by radio broadcast stations to handle emergencies arising out of storms such as that which recently crippled the middle west will be taken at a meeting to be held Wednesday afternoon at 2 o'clock at the Drake hotel". 

Los Angeles Times (April 27, 1925):

This article talks about how radio broadcast is so "rapidly becoming recognized as a far-reaching channel of publicity..." The radio is now becoming a source of getting news updates and a place to be entertained by talk shows on various topics such as politics. 

Present Day: 

The three articles that I found on ProQuest, Project Muse, and JStor collectively refer to the radio as a "hip" source of entertainment that includes a diverse set of music, comedy talk shows, political debates, sports updates, and contests. The radio can be broadcasted to every home around the world. People are also allowed to listen to the radio in their cars. There are also apps that customize playlists that play for you on the radio. These apps include: Pandora Radio, iHeart Radio, etc.  

From "telegraphy" to Pandora Radio, "Broadcast Radio" has changed significantly over the years. The first instantaneous movement of information and communication is known as "telegraphy". The name then transformed into the radio, and was used by navy ships to communicate in Morse Code. From there, the radio turned into what we use it for today-a source of entertainment and mass communication. It's safe to say that the purpose of the radio has stayed the same throughout its existence; however, the radio has become a bigger source of entertainment than what it was originally intended for.
