⁹ Electrical World, October 9, 1915, p. 790; About such pronouncements, Lloyd Espenschied, an engineer in the AT&T laboratory and a participant in the long-distance radio tests, later noted: “[T]he company was fearful that its own success [would] lead the public [to] believe that wires were about to be supplanted by radio, whereby they might sell their telephone stock! So, credit was given to no one, save a blanket commendation of its own workers, and the company began to preach the limitations of radio — the words spread all over creation, were not secret, were subject to interference, only a limited number of stations could operate in the common medium. … So much for the great radio events of 1915 — the company had a bear by the tail!” Quoted from a manuscript titled “Advent of Electronic Telephony,” Box 8, Lloyd Espenschied Papers, Division of Electricity and Nuclear Energy, Smithsonian Institution.

An historian of radio has written: “The least expensive vacuum-tube receiver [1922] was a one-tube set manufactured by Westinghouse and marketed by the Radio Corporation … for $79.50. General Electric receivers employed three tubes and sold for $250. And even at these prices for simple sets, it was a year before suppliers were able to catch up with orders on hand.” Quoted from McNicol, Donald, Radio's Conquest of Space (New York, 1946), 341–342Google Scholar.

³² Sales of sets grew rapidly. The gross sales figures for RCA in its first three years in the receiving set market were: (1921) $1,469,000; (1922) $11,286,000; (1923) $22,465,000. Figures from Archer, Big Business and Radio, 139.

³³ The 1922 Annual Report, Engineering Department, Western Electric Company (copy at Bell Telephone Laboratories, Murray Hill, N.J.), p. 44, stated: “During the year development work was carried out on receiving equipment and this resulted in the design and manufacture of a number of different types of receiving equipment. The types of receiving sets which have been designed cover the whole field efficiently and we are in a position to meet any reasonable commercial demand.” On the set in the White House, see letters from D. Sarnoff to F. P. Guthrie (April 30, 1924) and to J. G. Harbord (May 19, 1924), quoted in Archer, Big Business and Radio, 143, 145.
