It is the opinion of historians that in order to better understand
the present, you need to know the past. Searching for one's roots
in this world is big business. Online
type websites are used by thousands of people to research their
family histories, and some services don't come cheap. You can even
pay someone to dig into your past to assimilate all available information
and put it in a bound, printed volume. Here on RF Cafe, I research
and post a lot of our profession's past. While the individual topics
themselves might not bear significantly on the present, having an
insight into the people's mindsets and progression of technology
is - or should be - motivating. No, most modern televisions do not
process analog signals, use a CRT, have vertical and horizontal
hold adjustments, but then not too far in the future most televisions
won't be much like they are now. Engineers and technicians of today's
world have a distinct advantage over prior years' innovators because
with enough ingenuity and fortitude, just about anyone can successfully
bring a useful idea to market.

How Television Got Its Electronic "Eyes"
revolutionary as airplanes without propellers - that's how much
electronic television differs from the earlier mechanical television!
Whirling discs and motors required for mechanical television
were not desirable for home receivers. Pictures blurred and flickered.
But now, thanks to RCA research, you will enjoy all-electronic
television, free from mechanical restrictions - "movie-clear" television
with the same simplicity of operation as your radio receiver.
Such "let's make it better" research goes into everything produced
At RCA Laboratories, world-famous scientists and engineers are
constantly seeking new and better ways of harnessing the unbelievable
forces of nature ... for mankind's greater benefit.
Electronic television is but one example of the great forward
strides made possible by RCA research - opening the way for who
knows what new miracles?
When you buy an RCA radio or phonograph or television set or
any RCA product, you get a great satisfaction ... enjoy a unique
pride of ownership in knowing that you possess the finest instrument
of its kind that science has yet achieved.
Dr. V. K. Zworykin, Associate Research Director and E. W. Engstrom,
Director of Research at RCA Laboratories, examining the Iconoscope
or television "eye" - developed in RCA Laboratories for the all-electronic
television system you'll enjoy tomorrow.
