It's not just google, it's all media. The more embedded and authentic advertising looks the better it works. Magazine/newspaper ads exist as much as a pretext for the magazine to write nice things about their advertisers in reviews and such. The real product reddit sells, I think, is turning a blind eye when advertisers sockpuppet the hell out of the site. Movies try to milk product placement for as much as they can because it's more effective than regular advertising.
