1. Modern Trends in Broadcasting
Introduction to Broadcasting
January 17, 2011

2. Questions about the Future of Broadcasting
1. Will broadcasting be supplanted by the Internet?
2. Will “convergence” lead to a single delivery
system for multimedia services?
3. Which broadcast delivery systems (terrestrial,
satellite or cable) will become dominant for
digital TV?
4. Will the reduction in costs of computer
hardware affect broadcasting?
5. Will computers merge with TV sets?

3. The Future of Broadcasting
• Those making bold predictions
about the future should be aware
that many predictions made in the
past have proved to be
dramatically wrong – even when
made by experts with impeccable
credentials.

4. The Future of Broadcasting
The eminent scientist
Lord Kelvin stated in
1895 that “Heavier-than
air flying machines are
impossible” and in 1897
compounded this error by
saying that “Radio has no
future”.

5. The Future of Broadcasting
In 1943, the
chairman of IBM,
Thomas Watson
said: “I think
there's a world
market for,
maybe, 5
computers”.

6. The Future of Broadcasting
In 1977, Ken Olsen,
the founder and
president of Digital
Equipment
Corporation said:
“There is no reason
for any individual to
have a computer in
their home”.

7. The Computer vs. Broadcasting
Industry
The Computer Industry:
• the computer industry has achieved the
remarkable feat of persuading users that
they need to replace their computers very
frequently.
• This means that users of older computers
cannot run the latest software without
upgrading their hardware. This inflationary
spiral results in rapid obsolescence

8. The Computer vs. Broadcasting
Industry
The Broadcasting Industry:
• Manufacturers of televisions have much
greater problems. Ordinary TV sets cannot
evolve to products with greater
functionality. It is true that new features
can be added, such as widescreen,
surround sound and high-definition, but a
television essentially remains a television.

• What is Digital TV?
Digital television (DTV) is the
sending and receiving of moving
