Handheld black and white TV, featuring a 2-inch flat CRT that had just been developed. In a process almost like reverse engineering, the device technology was developed from a designer's sketch. Catching live broadcasts of breaking news or sports events appealed to people. Versions of the FD-200 were offered in the U.S. bearing football logos. It proved a hit, and sales topped 500,000 units. The first model was introduced as "Flat TV," after which the nickname "Watchman" stuck.
