You may have heard Johnny Ryan on this podcast before. Last year, he came on to talk about the ad tech industry and what needs to happen within it for it to thrive under the General Data Protection Regulation. Ryan says, while there's some movement in the direction he thinks will best serve the industry -- namely, advertising without collecting any personal data online at all, there isn't enough. He's worried that if ad tech companies don't transition, and fast, the economic impact will be something akin to the financial meltdown the U.S. faced a few years back. In this episode, Ryan discusses what he believes needs to change, and how, for the industry to save itself.
