Abstract :
This paper considers the American radio industry from the standpoint of its long-time economic trends, with special reference to the past and probable future public demand for broadcast receivers and vacuum tubes. The history of the anuual sales to each of the various markets for these is analyzed, equations are given for their long-time growth trends, and estimates of growth are projected ahead to 1947. Conclusions are stated regarding the probabilities of changes in the nature of the demand for initial and replacement receivers in the form of primary, secondary, automobile, and export receivers; and for vacuum tubes for initial equipment or replacement purposes.
