Google is Alphabet's core search and advertising business, and one of the world's leading AI research organizations. It operates Google Search, YouTube, Gmail, Google Maps, and the Gemini AI platform.
YouTube's recommendation algorithm uses deep neural networks to determine what video plays next, accounting for over 70% of all YouTube viewing time. The system has been linked to algorithmic radicalization and filter bubbles.
YouTube uses a two-stage deep learning architecture: a candidate generation network that selects hundreds of relevant videos from millions, followed by a ranking network that scores and reorders them by estimated watch time.

AI Overviews launched broadly in the US in May 2024. The feature uses Google's Gemini model to generate multi-sentence answers to search queries, significantly changing how users interact with search results and reducing click-through rates to publishers.
