Alphabet, the parent company of Google, earns nearly 90% of its revenue from Google services, mainly through advertising. Other revenue comes from subscriptions (YouTube TV, YouTube Music), platform sales (Play Store purchases), and devices (Pixel, Chromebooks, Chromecast). Google Cloud contributes around 10%, while investments in self-driving cars (Waymo), health (Verily), and internet access (Google Fiber) make up the rest.
