This is a good question. All I can speak from is the experience of my own family. We don't watch TV that includes ads. We don't really watch any TV shows that would include product placements. All of our browsers have multiple ad blockers running (First Party Isolation, Change Geolocation, AdNaseum, Ghostery, and Ad Block Plus), so very few ads in browsers. We don't have any magazine subscriptions. Where we live there are very few billboards or other road side advertisements. I'm sure they are exposed to ads, I'm just not sure from where.
