Problem: Given the question: Question: "what machine is mentioned first?" Context: "Eventually, when it was more common for electric recordings to be played back electrically in the 1930s and 1940s, the overall tone was much like listening to a radio of the era. Magnetic pickups became more common and were better designed as time went on, making it possible to improve the damping of spurious resonances.

Both of these high quality microphones became widespread in motion picture, radio, recording, and public address applications." Answer:
