In 1952 when this new item appeared in Radio-Electronics magazine, a transistor production rate of 8,500 per year was something to boast about. Most integrated circuits these days contain at least that many transistors. Western Electric, the telephone equipment manufacturing division of Bell Telephone, dominated the market with a whopping 6,000 per year. They were also the only company producing junction transistors, albeit on an experimental basis. The rest were point contact types like the Bardeen, Brattain, and Shockley prototype from December 1948, which was only three and a half years earlier. A typical transistor cost $18 in 1952, which is the equivalent to $197 today, per the BLS CPI Inflation Calculator. That was understandably considered an impediment to widespread adaptation of the transistor when a vacuum tube would set you back a buck or two.

Transistor Production at All-Time High Level

Transistor Production at All-Time High Level, July 1952 Radio-Electronics - RF CafeThe transistor has emerged from the laboratory to become a full-fledged production item. According to reports made at the Symposium on Progress in Quality Electronic Components held in Washington early in May, nearly 8,500 transistors were being produced monthly. Six companies were actually producing transistors in commercial quantities, and two others expected to be ready to manufacture in appreciable quantities within a few months.

Western Electric, with 6,000 transistors per month, was producing the bulk of the output. Raytheon followed with 1,000 per month, with General Electric and RCA making 800 and 400 respectively. RCA expected to up its output to between 2,000 and 3,000 per month by the end of the year, and other companies indicated that sharp increases in production were expected, though the exact quantity to be produced would depend on orders received.

Practically all the transistors now being manufactured or slated for immediate future production are of the contact type. Only Western Electric reported manufacture of junction transistors - on an experimental basis only, with an output of less than 100 per month.

Military procurement accounts for 6,000 transistors per month; the output of Western Electric being allocated as a result of an arrangement between the military departments and the company.

The limited production still hampers widespread use of the transistor, as a manufacturer would be unable to take a contract for equipment requiring a couple of thousand transistors unless he could obtain the whole unallocated output of the country for a month, or large fractions of it over a proportionally longer time. Price is the other barrier to wider use. The units are listed in mail order catalogs today at $18 each. Presumably those sold in larger quantities are somewhat - but not greatly - cheaper. At a price so much greater than the vacuum tube, the transistor becomes practical only when extreme miniaturization or other special necessity disqualifies the tube for the application.

The table below, abstracted from a paper presented by Lt. Colonel W. F. Starr at the Washington symposium, shows the present situation in transistor production.
