It never occurred to me to wonder where Motorola got its name. Recently, I heard this fascinating tidbit and followed up — it appears to be true!
From Motorola’s own timeline:
In 1930 Galvin Manufacturing Corporation introduced the Motorola radio, one of the first commercially successful car radios. Company founder Paul V. Galvin created the brand name Motorola for the car radio — linking “motor” (for motorcar) with “ola” (which implied sound). Thus the Motorola brand meant sound in motion.
Today, Motorola’s cell (mobile) phones give a whole new meaning to “sound in motion.”
