Do you have any idea on what the Chromecast revenue stream was? I couldn't find it after a cursory look. I'm wondering if it's lumped into one of the "other" categories.

I think part of the distinction is how "success" is being defined. An product may be innovative and market defining, yet still not contribute much to the bottom line. It's still cool to work on, but these companies are still trying to make money at the end of the day. I assume their moonshot ideas still have the explicit long-term goal of being profitable.
