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. 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.

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. Today

many different signals.The evolution ofTV
broadcasting is shifting from satellite
technology to the internet.

6. Radio Broadcasting
Radio transmission is sent via radio waves
from a transmitter to a receiving antenna.
This was the traditional process by which

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.
