How the shows you watch determine which candidates’ ads you see

We took data for 51 of the shows with the most 2016 advertising and made a tool that lets you compare which shows you watch with the campaigns most likely to focus their ad spending on those programs. This isn't a terribly refined calculation; we make no promise that we can tell you your party registration or anything like that. What it will tell you is, given only these shows, which candidates would be most likely to run spots that you'd see.
