Chapter 5 - Popular Radio and the Origins of Broadcasting Flashcards
Telegraph
Inventer in the 1849s, it sent electrical impulse through a cable from a transmitter to a reception point, transmitting Morse code.
Morse Code
A system of sending electrical impulses from a transmitter through a cable to a reception point; developed by the American inventor Samuel Morse.
Electromagnetic Waves
Invisible electronic impulses similar to visible light; electricity, magnetism, light, broadcast signals, and heat are are part of such waves, which radiate in space at the speed of light, about 186,000 miles per second.
Radio Waves
A portion of the electromagnetic wave spectrum that was harnessed so that signals could be sent from a transmission point and obtained at a reception point.
Wireless Telegraphy
The forerunner of radio, a form of voiceless point-to-point communication; it preceded the voice and sound transmission of one-to-many mass communication that became known as broadcasting.
Wireless Telephony
Early experiments in wireless voice and music transmissions, which later developed into modern radio.
Broadcasting
The transmission of radio waves of TV signals to a broad public audience.
Narrowcasting
Any specialized electronic programming or media channel aimed at a target audience.
Radio Act of 1912
the first radio legislation passed by Congress, it addressed the problem of amateur radio operators cramming the airwaves.
Radio Corporation of America (RCA)
a company developed during the World War 1 that was designed, with government approval, to pool radio patents; the formation of RCA gave the United States almost total control over the emerging mass medium of broadcasting.
Network
Broadcast process that links, through special phone lines or satellite transmissions, groups of radio or TV stations that share programming produced at a central location.
Option Time

Federal Communications Commission (FCC)
An independent U.S. government agency charged with regulating interstate and international communications by radio, television, wire, satellite, cable, and the Internet.
Transistors
Invented by Bell Laboratories in 1947, these tiny pieces of technology, which receive and amplify radio signals, make portable radios possible.
FM
Frequency modulation; a type of radio and sound transmission that offers static-less reception and greater fidelity and clarity than AM radio by accentuating the pitch of distance between radio waves.
AM
Amplitude modulation; a type of radio and sound transmission that stresses the volume or height of radio waves.
Format Radio
The concept of radio stations developing and playing specific styles (or formats) geared to listeners’ age, race, or gender; in format radio, management, rather that deejays, controls programming choices.
Rotation
In format radio programming, the practice of playing the most popular or best-selling songs many times throughout the day.
