Alphabet is a holding company with Google, the Internet media giant, as a wholly owned subsidiary. Google generates 99% of Alphabet revenue, of which more than 85% is from online ads. Google's other revenue is from sales of apps and content on Google Play, YouTube Red and cloud service fees, and other licensing revenue. Alphabet's moonshot investments are in its other bets segment, where it bets on smart homes (Nest), technology to enhance health (Verily), faster Internet access to homes (Google Fiber), self-driving cars (part of X), and more.
