There is a bit of Anime on your Ads.
Anime
Anime with blatant product placement.
Not counting short ads or anime adaptations of games/visual novels.
The appearance of product placement must be frequent in most of the anime eps.
Not including parodies like "WcDonalds", "Prangles", "Bocky" or "Guugle" either.
Feel free to provide more info if you saw any of these anime or if you found an anime with a lot of product placement.
Haikyuu!!, Yuru Camp, Code Geass, AoButa and Ga:Rei Zero suggested by LittleStar
