Some investors have worried that generative AI, the tech that underpins Google’s AI summaries, could cannibalise the firm’s search business

Alphabet’s Google is beginning a wide roll-out of ads that will be displayed within and alongside the AI-generated summaries that appear at the top of some search results – a move meant to show investors that costly artificial intelligence projects can generate revenue.
Some investors have worried that generative AI, the tech that underpins Google’s AI summaries, could cannibalise the tech giant’s search business, which is still by far its most lucrative unit. The company said in May that it would start testing ads in these search summaries, called AI Overviews, and now it is rolling the feature out to anyone in the US using Google’s mobile app.
