  1. For hard-core music lovers, the Zune’s a gem. It blows the iPod off the map in music discovery and downloading.

  2. Radio and the Origins of Broadcasting

  3. Novelty Stage • Samuel morse • Telegraph (wires) • Morse Code Video of telegraph

  4. Novelty Stage what about wireless? How do you transmit a signal through the AIR?

  5. Novelty Stage 2. James Maxwell His equations theorized that electricity, magnetism and even light are all manifestations of the same phenomenon: the electromagnetic field.

  6. Novelty Stage 3. Heinrich Hertz • Proved Maxwell’s theories • Identified Electromagnetic waves

  7. Novelty Stage Hertz (Hz) can be used to measure any periodic event; the most common use for hertz is to describe frequency of rotation, in which case a speed of 1 Hz is equal to one cycle per second.

  8. Novelty Stage 4. THREE GUYS WHO INVENTED THE DEVICE TO TRANSMIT A SIGNAL THROUGH THE AIR (1894) A. Guglielmo Marconi vs. B. NiKola Tesla vs. C. Alexander Popov • Who invented Wireless telegraphy?

  9. Novelty Stage MARCONI

  10. Marconi’s Invention (Dramatization) HAD IMPLICATIONS FOR SHIP TO SHORE TRAVEL

  11. Tesla

  12. POPOV

  13. Novelty Stage POPOV(Dramatization)

  14. Tele = far off Telegraph Graph= writing Telephone Phone= sound Phonograph W I R E L E S S T E L E G R A P H

  15. Novelty Stage 5. Reginald Fessenden • Wireless telephony: • transmitted voice and sound

  16. Novelty Stage 6. Lee De Forest • Wireless telephony: amplified sound (monkey face)

  17. Novelty Stage

  18. Entrepreneurial Stage

  19. Entrepreneurial Stage • Ship-to-shore communication

  20. Entrepreneurial Stage • David Sarnoff and the Titanic

  21. Entrepreneurial Stage • “Wireless” became a huge hobby

  22. Entrepreneurial Stage "I remember it was 10 or 11 o'clock at night and all at once, this voice appears. And I remember letting out a yelp or a shout of some sort and my dad, who had just gotten out of the bath, came in wrapped in a towel to make sure... that something hadn't happened to me. I said, 'Dad, look, I hear this fellow talking.'"

  23. Some Key Developments… • Radio Act of 1912 • You need a LICENSE to operate a radio • WWI • Radio is an important war tool • U.S. wants to control Global radio

  24. Some Key Developments… 1915: Over 20 companies selling point-to-point radio equipment: e.g. • AT&T (transmitters) • General electric (U.S.) (Receivers) • American Marconi (Britain) (both) • (marconi was the biggest and best)

  25. Some Key Developments… U.S. develops a “plan” to ensure powerful radio technology would fall under U.S. control. 1. Establish new company, anchored by GE, called RCA (Radio Corporation of America), To pool patents. RCA is a private-sector monopoly. 2. Using GE, weaken British Marconi by not selling them key components, and then BUY its american assets (american Marconi) 3. Use RCA to oversee radio patents from GE, AT&T, Westinghouse, American Marconi and the navy. Standardization. =The beginning of American domination over communication technology

  26. Some Key Developments… • THE UK MODEL: In 1904, Great Britain decides to develop A state-supported broadcasting system. • The UK Funds the BBC (British Broadcasting Corporation)

  27. Mass Medium Stage

  28. Mass Medium Stage • KDKA, Pittsburgh, 1920. “First” station to broadcast music and talk (disputed) • BROADCASTING vs. POINT-to-POINT • First ads, 1922

  29. Radio: a DEMOCRATIC medium • Education • Religion • Workers • Businesses (jewelry stores) • Entertainment • News (VIDEO “Radio Network Broadcasting”)

  30. Tufts University, 1922

  31. Education
