  5. The History of Broadcast Media How it all began …

  6. When it all began • The first message sent by wire (telegraph) from Washington DC to Baltimore in 1884 • The FIRST broadcast message • What is broadcasting? • “… the distribution of audio and/or video signals which transmit programs to an audience. The audience may be the general public or a relatively large sub‐audience, such as children or young adults.”

  7. Broadcasting • Sending one message to a large group or audience • Broadcasting has many inventors • Physicists James Maxwell and Heinrich Hertz demonstrated the existence of electromagnetic radiation, i.e. energy waves that travel through space • Three main inventors of wireless communication: Marconi, Fessenden & DeForest

  8. Guglielmo Marconi • Saw a demonstration of radio waves while in college • Realized the biggest potential use for wireless communication, was in instances where wires were not possible (ships) • Began experimenting with transmitters and receivers • Eventually, he was able to send a radio signal a little over a mile • In December 1901, he sent the first radio telegraph across the Atlantic Ocean

  9. Reginald Fessenden • Marconi was sending Morse code – no one had yet to send voice over radio waves • A new way of generating radio signals had to be developed • To transmit voice or music, a continuous radio wave was needed • While working at General Electric, Fessenden built a high speed alternator that allowed for the continuous wave • Tested on Christmas Eve 1906, Fessenden’s voice was the first on the air – then he played some violin music and read a few passages from the Bible before signing off.

  10. The Crystal Set • In 1910, the most popular way of receiving radio signals was using a crystal set – some minerals were able to pick up radio waves • They were cheap and easy to assemble, but they couldn’t amplify the signals very well

  12. Lee DeForest • Something that could boost weak signals was needed • Lee DeForest created the Fleming valve – which acted as an amplifier to boost weak radio waves in 1906 • Hooking up a few of these valves could amplify signals millions of times • He named this invention the audion • The audion evolved into the vacuum tube, and was the basis for all radio transmission until the 1950’s, when the transistor replaced it

  13. Boardrooms and Courtrooms • Now that radio has tested as a viable medium, what to do next to make it successful? • Legal issues: Radio’s main use was still ship‐to‐ship and ship‐ to‐shore communication • Many companies interested in radio: Marconi’s British Marconi & American Marconi, General Electric, AT&T and Westinghouse

  14. Who owns what? • Each of these companies owned patents for different types of functions and technologies • No one had patents that covered the entire process of developing transmitters and receivers • Each company went ahead and made them anyway – resulting in patent infringements

  15. WW1 and Radio • All US Navy ships were equipped with radio • In 1917, when the US entered the war, the government took control of all radio operations, in the interest of national security • The Navy assumed responsibility for patent infringement – meaning the various companies could pool resources to improve radio communication

  16. RCA • Commercial interests were opposed to the government’s control over radio after the war was over • Giving the Navy control over radio was never voted on • The stations were still owned by Marconi – a British company • Navy suggests to General Electric they purchase American Marconi and create a new company – called RCA (The Radio Corporation of America)

  17. Patents problems • After the Navy gave up control, patent issues were prevalent once again • RCA entered into a cross‐licensing agreement with GE, AT&T and Westinghouse that enabled all the companies to use each other’s patents • GE and Westinghouse agreed to manufacture radio equipment; RCA would sell it; AT&T would build the transmitters

  18. 1920’s • Radio came on the scene to the general public • KDKA in Pittsburgh became the first radio station under Frank Conrad in 1920; he played phonograph records and read from the newspaper • Westinghouse quickly started other stations • In 1922 there were 28 radio stations; in 1923, there were 570 • By the end of the 20’s half of American homes had a radio

  19. Money problems • RCA was making $11 M selling radios, while AT&T made $3 M – prohibited to sell radios according to the post‐war agreement • AT&T sold its radio operations, and was granted a monopoly over wire interconnections that enabled radio networks

  20. Radio Advertising • Radio was expensive to run – a way to make money to keep it afloat was needed • AT&T developed a system where anyone who had a message to deliver would come to the station, give the message, leave money, AT&T sent the message (toll broadcasting) • This was soon the same principle applied to radio advertising!

  21. WEAF • WEAF was the first station to have commercial advertising, August 28, 1922 • Rising operating costs were forcing other stations off the air • Initially, people did not want advertising on the radio • There was even talk in Congress to ban it (but we all know that didn’t happen!) • By 1929, radio advertising was a $20M industry

  22. How networks grew radio • There were many radio stations that needed programs • Many radio programs, and their talent, were located in New York, Chicago, Hollywood. • Smaller cities wanted access to those programs too • Networks were developed • Based on the technology AT&T had to wire stations, networks were possible • Networks shared programs to their affiliates • Affiliates = individual stations, in different cities

  23. RCA and the birth of Networks • David Sarnoff (president of RCA) set up a new company in 1926 to separate the parent company from the broadcast organization • The National Broadcasting Company was born • The “Red” network consisted of stations from AT&T, and the “Blue” network comprised stations originally owned by RCA, Westinghouse and GE • By 1933, NBC had 88 stations in its network

  24. Networks grow • The Columbia Broadcasting System was founded in 1927 by William S. Paley – starting with 16 stations, and by the end of 1933 had 91 stations • Mutual Broadcasting System started in 1934 • Advantages: brought programming to rural areas that previously didn’t have radio programming; contributed to radio’s growth

  25. Early Rules & Regulations • Attempts to regulate the new medium of radio can be traced to 1903 • Wireless Ship Act of 1910: required certain passenger ships to have wireless communication • Titanic disaster: many were saved due to wireless distress signals, however, the signal was interfered with due to unregulated amounts of stations on the air simultaneously • Trivia: one of the first operators to relay the Titanic’s distress call was David Sarnoff – the future president of RCA and champion of Color TV

  26. Early Rules & Regulations • Radio Act of 1912: required stations to be licensed by the Secretary of Commerce – who would assign wavelengths and time limits • Interference was still a big problem: federal control was needed • Radio Act of 1927: radio frequencies could not be owned, but they could be licensed for use; license holders had to operate in the public interest; gov’t censorship was forbidden; creation of the Federal Radio Commission to enforce the new laws • Communications Act of 1934: replaced the FRC with the FCC – the Federal Communications Commission

  27. Radio 1930-1948 • Radio grew at a phenomenal rate, becoming an integral part of American life • $40M spent on radio advertising in 1930; $506M in 1948 • Growth continued despite another war and economic depression • FM broadcasting: invented by Edwin Armstrong, it was publicly demonstrated in 1933 • FM was less prone to static, and could broadcast in stereo • FM did not catch on (at this time) because AM radio was already so successful, RCA was unwilling to invest • FCC ruled NBC was monopolistic ‐ they sold off the Blue Network, which eventually became ABC

  28. Impact • Primary source of home entertainment • Social power: • 1938 Orson Welles produced "War of the Worlds" and caused mass hysteria • Radio took advertising revenue away from newspapers, and news broadcasts eliminated the need for extra editions of newspapers
