Radio daily (Oct-Dec 1949)

Scientists at RCA Laboratories solve exacting problems within the "nothingness" of vacuum tubes. inside j/o/y of Beffer7e/ev/s/brt Now television is flashing visual entertainment, news, and educational material to millions of people. The "inside story" of its rapid growth is the history of some remarkable tubes. Inside these tubes, electrons are put to work— to perform, for your benefit, the miracle of long-distance vision. The screen of your direct-view television receiver is actually the face of a tube — the kinescope developed by Dr. V. K. Zworykin and his colleagues of RCA Laboratories — on which electrons in motion "paint" pic tures. A tube, too, is the "eye" of RCA's supersensitive Image Orthicon television camera, which can "see" clearly by the light of a match. And since you asked for big-picture television, they developed projection receivers —also a way to "weld" glass and metal, thus speeding the production of 16-inch directviewing tubes ... at lower cost. To these basic "firsts," RCA scientists have added advance after advance, which are daily bringing television into the lives of more and more people. How you profit Advanced research in television tubes is just one way in which RCA Laboratories work in your interest. Their leadership in science and engineering adds value beyond price to any product or service of RCA and RCA Victor. Examples of the newest advances in radio, television, and electronics— in action— may be seen at RCA Exhibition Hall, 36 West 49th Street, New York. Admission is free.
