I was curious too - "Paul Galvin wanted a brand name for Galvin Manufacturing Corporation's new car radio, and created the name “Motorola” by linking "motor" (for motorcar) with "ola" (from Victrola), which was also a popular ending for many companies at the time, e.g. Moviola, Crayola."
Neither "googol" nor "atari" (a very clever Japanese import) were common English words. Stuff like "lambda", or "spark", or "react" are more or less everyday words, with well-established previous everyday meanings.
