Transcribed Image Text:Subsquent inventions included
the color television system in 1946,
cable television in 1948, satellite
television in the 1970s and in recent
years, the Internet Protocol Television
(IPTV). IPTV allows audio and video
to be transmitted using internet
file transmission protocols that
enable viewers to watch programs
on computer screens instead of
television sets. Indeed broadcasting
with images, sounds, and motion has come a long way, but is still evolving.

led to radio broadcasting-where one person could talk to a mass audience.
This was the start of a most significant feature of twentieth century media,
the rise of one-way communication.
Broadcasting initially involved only the electronic transmission of radio
signals. Further technological developments in the early 20th century would
expand broadcasting to the transmission of television signals, that is, sound
and visual images.
Television grew out of a series of technical developments that were
simultaneously taking place in Europe as well as the US. In the US, two
inventors working independently claim to have developed a system for
transforming a visual image into an electronic signal in 1927, Vladimir
Zworykin and Philo T. Farnsworth. At about the same time in Europe, the
works of John Logie Baird of Scotland and Sir Isaac Shoenberg of Britain
led to the development of the television-broadcast system.
Commercial television in the US began in 1939 with the coverage of
Franklin Roosevelt opening the World Fair in New York. In Britain, the British
Broadcasting Corporation (BBC) broadcast the procession of the coronation
of King George from Hyde Park. Germany claims to have operated the world's
first regular television service during the time of Adolph Hitler. Propaganda
broadcasts were transmitted to specially equipped theaters.
