In 2015 we can read at motorola.com: "85 years – 1930":
"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 Motorola for the car radio—linking "motor" (for motorcar) with "ola" (which implied sound). Thus the Motorola brand meant sound in motion."
