It is the opinion of many 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
family tree 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"
As 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 by RCA.
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.
