    Great piece of work, Ed.  Well done.

    The only additions I would make are related to radio station WWV, which made time available by shortwave to small boat sailors across the 7 seas.

    • In 1953, Sony bought a license for $25,000 from AT&T to manufacture transistors.

    • By 1958, Sony went from being a company with 7 employees to one with 500...and had begun selling what eventually became millions of transistor radios.

    • In 1966, radio station WWV began broadcasting shortwave time signals around the world from Fort Collins, Colorado.

    I think the combination of transistor shortwave radios, station WWV, and Seiko's quartz watch is what finally allowed the St. Hilaire intercept-method to come into its own among small boat sailors.
