t has, almost certainly, happened to you. You have a conversation in person, you mention something specific, and minutes later, there’s an ad for it on your phone. For the past decade, most of us have come to the same conclusion: Our phones must be listening. But are they, really? I wanted to dig into the “phone listening” theory — where it came from, what the official research says, and what’s actually happening every time you load an ad on the internet. What I learned is that creepy ads are just the tip of the iceberg, powered by a system auctioning off our location, identity, and behaviors to countless companies vying for our attention… and others looking for something else.
