First public radio broadcast

History of Radio By: Kaitlyn Murphy

  • Telegraph

    According to the textbook, "The Media of Mass Communication", Samuel Morse invented the telegraph in 1844. This invention was able to send dashes and dots that then were decoded into a message. By using the dashes and dots, his first message that he sent said, "What hath God wrought". (Vivian 36)
  • Phonograph

    The first recoding machine called the Phonograph was invented by, Thomas Edison. This was a key point in media technology history that pioneered sound media (Vivian 36)
  • Granville Woods

  • Heinrich Hertz

    Heinrich Hertz
    Heinrich Hertz discovered radio waves by setting up two coils separate from each other, when he electrified one, the other one responded. This proved that radio waves could be sent to each other through the air. (Vivian 37)
  • Guglielmo Marconi

    Guglielmo Marconi
    Guglielmo Marconi was able to successfully transmitted the first wireless message. Marconi discovered that he was able to send messages farther and farther apart using an antenna. (Vivian 37)
  • First Atlantic Wireless Message

    Marconi was able to successfully send the first radio transmission across the Atlantic Ocean. This message was sent over 2,000 miles (England to Canada) stopping anyone who was skeptical of this in their tracks. ("Marconi Sends First Atlantic Wireless Transmission")
  • Audion

    Lee DeForest invents a vacuum tube device called, the Audion. The Audion is able to magnify weak electrical signals, making voice transmission possible ("Lee De Forest")
  • News Radio

    Lee De Forest and a New York newspaper, the American, made an agreement to broadcast election returns. Hundreds of people were able to listen to the election information. (Vivian 133)
  • KDKA

    KDKA was established in Pittsburgh, and became the world's first commercial radio station (Vivian 130). KDKA’s first broadcast was a live report of the presidential race between Warren Harding and James Cox (and this time hear the correct information) (Vivian 133). The start of KDKA was the turning point of mass media and communication. This brought broadcasting to a new level with more opportunities.
  • Federal Radio Act

    The overlap in radio signals started to become a problem, causing the government to became a stakeholder under the Federal Radio Act. This organized the system by having the government act as a station licensing system. Under the Federal Radio Act, the Federal Radio Commission established ownership that was able to put limits on radio station broadcasting. This act also regulated stations frequencies to prevent overlap in signals, helping with air clutter. (Vivian 125)
  • Invasion From Mars

    CBS broadcasted a program called, “The War of the Worlds”, for a Halloween episode. With the high volume of listeners on the Mercury Theatre on the Air, it caused panic throughout the nation. ("Welles Scares Nation”)
  • Gordon McLendon

    Gordon McLendon
    After World War II people became less interested in the news and the long stories that they were airing. Gordon McLendon capitalized on this making a “rock ‘n’ roll” type format with his radio show. He podcasted very short stories with a three-minute streaming of music. (Vivian 133)
  • National Public Radio

    National Public Radio
    The 1967 Public Broadcasting Act established the Corporation for Public Broadcasting, which supported noncommercial radio. National Public Radio joined the radio airwaves with their first program called “All Things Considered”. National Public Radio was different from commercial radio because the stories were longer in length and also were not the top breaking stories. “All Things Considered” was NPR’s popular program, still exiting to this day. (Vivian 134)
  • Talk Radio

    Talk radio started to become main stream in the 1980's. Talk radio took the approach of having listeners call in to talk about many different events and issues going on in their communities or even around the world. Today talk radio as many different forms of shows and are broadcasted all day and all night long. (cont. on next slide)
  • Talk Radio (continued)

    Our textbook, "The Media of Mass Communication", estimates the amount of listener each host pulls in; Rush Limbaugh is estimated at 26 million, Michael Harrison is at 14.3 million and Sean Hannity is sitting at 13.3 million. This just proves that talk radio is still a huge key player in radio today. (Vivian 134)
  • Satellite Radio

    Satellite Radio
    When first released satellite radio changed the game for listening to radio. Sirius and XM radio were developed, which used satellites to transmit their signals. This made for clear sound and a variety of stations to listen to. (Vivian 136)
  • SiriusXM

    In 2007 Sirius and XM radio emerged making SiriusXM. SiriusXM in a way was looked at as a luxury to have, when you bought a new car you got a limited time subscription to SiriusXM. After the subscription people would then pay to have it available to them. (Vivian 136)
  • Cell Phones and Radio

    With the advancement of cell phones more people have been able to access the radio. You are now able to stream podcasts, music, and news through your smart phone.("Activate Your Cell Phone's FM Chip.")
  • Todays Advancements in Technology

    Seeing from where we started to now there is so much new technology or technology that is coming out at a rapid pace. Radio was something that started by being listened to in the house, moving to cars and now available on our smart phones. Smart devices and the Internet played a key role in advancing the radio.(Vivian 136-138)

  • Todays Advancements in Technology (Continued)

    Being able to have the internet accessible to you at all times made it for the radio and podcasts to be at your fingertips. With the internet available in cars it also made for podcasts to be accessible while you are driving, advancing the radio even more. (Vivian 136-138)
