What ever happened to Farnsworth’s patent? We might recall that in the 1870s, Bell had managed to force Western Union’s retreat from telephony by means of a patent lawsuit. By such means, too, Sarnoff himself had pushed AT&T out of the radio industry in the 1920s. Farnsworth might have done likewise to RCA in the 1930s. But in Sarnoff he was facing ruthless genius not to be cowed by any man or law.
