YOU enjoy movies more because of radio. Radio helps make movies so interesting that the annual attendance in the United States equals twice the population of the world. Yet few realize that the reproduction of voices and the whole range of sound that makes pictures live — is a laboratory product based on research in radio and sound.
Because the recording and reproduction of sound involves so many principles which have grown out of radio, research in RCA Laboratories has been, and continues to be a big factor in creating finer motion picture sound entertainment. This work is closely connected with research and actual practice in making Victor Records and operating the National Broadcasting Company.
Here is another example of the way in which RCA uses research to develop services of benefit to the whole world. It was research that built the world-wide radio message service of R.C.A. Communications. . . research that developed the RCA direction finder' ' and other safety devices for ships at sea which the Radiomarine Corporation of America supplies . . . research that has made RCA Victor Radios and RCA Victrolas outstanding in the field of radio and record entertainment.
Because the Radio Corporation is active in every field of radio, the sum total of its research benefits every person engaged in the sale of radio products. The efforts of RCA make radio more attractive to those who listen and thereby improve the opportunities of those who sell radio instruments. This is in line with the RCA policy of making radio serve more people in more ways and serve them better in all ways.
