Bill Gross, founder of Overture (the company that created paid search) and now ProRata.ai, says that generative AI is fundamentally rewriting the rules of search - which means marketers, advertisers, and customers must all adapt to new ways of discovering products. Gross explains ProRata’s business model, how advertising will evolve inside AI-generated results, what a fair-value model for publishers and creators might look like, and how brands can stay discoverable and trusted as attention shifts away from search pages toward GenAI chat models.
