Was tv made before truck radios?

Answer 1

The earliest production radios for automobiles (including trucks) were introduced by Motorola in 1930. While the fundamental inventions necessary for television had been made by that time, they did not appear in production (electronic, as opposed to electromechanical) television receivers until the mid-1930s. In the US, Broadcast Television signals were not standardized until 1941, when the first commercial broadcast television licenses were issued.

If you mean two-way radios for trucks, then it's practically a tie. Two-way radios were being installed in fire trucks as early as 1938--exactly the same time that television was being introduced.

This question could be debated endlessly, since it really depends on what form of experimental television you would accept as the starting point.
