Google is just misspelled 10^10. I don't see how that is "professional" more than google just built its brand out of thin air.

I can definitely give credit to Google for inventing the word though. So few people try making companies without their names having some second meaning besides "my company".

It's easy to say google however. Yahoo and Bing are easy too. Compare this to spelling "duckduckgo" especially for non-English speakers.
