Have you played Raid Shadow Legends, or subscribed to NordVPN because a YouTuber talked about it? I don't know anyone who has played Raid, and I am kind of curious if it is actually a thing.
I can had honestly say that I haven't bought anything based off these advertisements, but they must attract reasonable attention because they are so common.
And I know that a lot of the ads happen because YouTube demonitises everything. But the ads mist bring in enough money to make them worthwhile.
Once the YouTuber starts his ad talk I just skip ahead in the video until it's over. Irregardless I always tend to ignore anything I hear on an advertisement. I'm sure all humans are subconsciously affected by ads they hear like that, but I can't think of a single instance ever where I heard a placement ad like that where I even looked up what the product actually was.
