How the $500 Billion Attention Industry Really Works
About this episode
The episode dissects programmatic advertising, the business model funding most of the internet. Hwang, former director of the Harvard-MIT Ethics and Governance of AI Initiative, Google's former global public policy lead for AI, and author of Subprime Attention Crisis, explains how real-time auctions — billions daily — commodify attention into tradable units, with Google's AdWords keyword marketplace as the founding innovation. He argues the market is a bubble: studies suggest 56 percent of display ads never reach a person through fraud, 41 percent of campaigns miss their target from bad data, and 56 percent of delivered ads are never seen. He rejects the idea that ads cause outrage culture — creators chase audiences under any model — and worries that attention, a collective good, is being degraded. The conversation closes on AI: large language models could either replace search's array of links with a synthesized voice or supercharge micro-targeted persuasion.
