I've never understood how anyone was able to engineer, design, manufacture, and sell a TV within the first year production resumed. If you notice, most large companies like Philco, Zenith, and GE, introduced TV's in '48. That makes sense.

The government never stopped companies from engineering during the war, only from mass production. Many firms were still engaging in civilian product development research even in the middle of the war....As long as you did not use up goods needed for the war effort uncle sam could care less. Heck IIRC the RCA projection CRTs and optics were under development during the war.
I'd imagine a number of firms designed products that they could roll out as soon as consumer production could be resumed.
