  1. 1. RADIO AND TELEVISION Blast-off to the Future in CommunicationTechnology
  2. 2. Intro  In the 1950’s when television and radio started to become popular, there would be a central station that would send out a signal so that every user could receive the message.  This signal was sent in a series of radio waves from the central broadcasting station to the antennas of the receiving television or radio broadcasting unit.
  3. 3. Evolution  In a sense the evolution inTV and radio media resigns in the they way each unit receives signals from transponders, which are any kind of communications Satellite because they can “transport,” “receive,” and “respond” to any message.  The firstTelevision Media Satellite was invented in 1962 and it utilized microwave technology instead of radio wave technology.
  4. 4. Continued…  Microwave communication refers to the technology of transmitting information by the use of the radio waves whose wavelengths are conveniently measured in small numbers of centimeters.  This technology was invented in 1962 but did not become popular to the everyday consumer until the 1990’s.
  5. 5. Today  TodayTelevision media is acquired through many different signals.The evolution ofTV broadcasting is shifting from satellite technology to the internet.  With such inventions asThe “AppleTV” and Hulu.com,Television broadcasting is becoming very popular over the Internet.  The AppleTV enables people to surf the web through their television monitor severely broadening the entertainment spectrum.
  6. 6. Radio Broadcasting  Radio transmission is sent via radio waves from a transmitter to a receiving antenna. This was the traditional process by which people acquired entertainment and news.  This process of broadcasting from a single frequency to an AM/FM radio has been the popular standard for many years; however, with the rise in efficiency in XM Radio, satellite radio is gaining popularity.
  7. 7. Satellite Radio  Satellite Radio uses a digital radio signal that is relayed through many different satellites which allows radio listeners to receive messages throughout a larger geographical area.  Some of the popular names in Satellite Radio are “Sirius,” “XM,” and “Worldspace.”
