| Hello, From sitcoms to sports, you might expect the ads seen on streaming TV platforms or devices like Roku to be the same for everyone watching the same show. But this election season, some Americans are being inundated with targeted political ads — and others won't see any at all. Why? Unlike traditional broadcast or even cable television, video streaming services in the U.S. can microtarget political campaign ads with scary levels of precision. And since there are few federal laws regulating streaming platforms and almost no transparency into how they work or which ads they accept ... voters have no way of knowing who can target them, how, and why. With a consequential election season underway in the U.S., we believe it's important to shed some light into how streaming services are handling political ads, so we created a report card to help you understand what’s going on. Explore the Report Card Our researchers dug into the policies of six top streaming platforms: Hulu, Roku, Tubi, CBS All Access, YouTube TV, and Sling TV — collectively these platforms have hundreds of millions of subscribers. We pored over ad policies, investigative reporting, marketing materials, and user settings. We asked questions like, "Does the platform fact check political ads?" and "How sophisticated are platforms' targeting capabilities?" The research shows that opacity, not transparency, is the status quo. None of the platforms we researched offered ad transparency libraries or archives, except for YouTube TV. That's right – just one out of six. Some streaming platforms fared far worse than others in our report card. See their grades now and learn more about the research. You can also help spread the word by sharing the report on Twitter, Facebook, or by email. Thanks for checking it out. — Becca, Kaili and the rest of the Mozilla team |
