RCA and the 630TS.

Inglis, Behind the Tube(1990):
At the end of World War II, RCA's engineering and production facilities were put into high gear, and in 1946 it introduced the 630TS, which is sometimes described as the Model T of the television industry. (The 6 was the model number, 30 was the number of tubes, and TS meant television and sound.). . .The 630TS clearly put RCA in the lead among televion receiver manufacturers, and RCA surprised the industry in 1947 when, motivated by what it perceived as enlightened self-interest, it made its manufacturing drawings available for free to its competitors. Most of the other companies were cynical about RCA's motives, but RCA was probably sincere when it stated that the industry was bigger than any single company and that helping its growth would help everyone, including itself. RCA immediately increased the market for its picture tube, NBC's audience, and its income from patent licensing and technical aid, (p. 232).
