I don't agree. I watch YouTube tech, math, and science content every day and that's not my experience. There are a small set of products that seem to be everywhere for a while, occupying a minority of sponsor segments. But in most sponsor segments I see one-off products that I'll never see again on any channel. On the rare occasions where they show something that looks really useful to me, I'd have to take a note because it's so unlikely to be a product I will encounter again. I don't take those notes, so I've seen a lot of great-looking products that I'll never buy due to forgetting they exist by the time they would be useful to me. When I need something I tend to browse for what's available and/or look at reviews with a skeptical eye, as I'm sure many people do. So the sponsor segments aren't that effective for me. But I wouldn't call them repetitive, except for a few products that come up a lot.
