Introducing AI Summaries, YouTube and X in Discover Monitoring

In key markets like the US, Brazil, and Mexico, AI Summaries already make up 51% of the feed. When they appear, AI Summaries often display multiple publisher logos but provide a single actionable click, which in most cases plays an inline YouTube video (77% in the US, 100% in Brazil and Mexico). Deeper in the feed, AI dominates even more, quietly replacing publisher links. At the same time, YouTube and X are taking growing chunks of Discover real estate, while traditional aggregation models are losing ground.
