Those are just the most obvious product placements, recognizable to folks who can't read all the little japanese labels on things that appear in the background.
There are also shows which are nothing but vehicles for products.
Of course this isn't just a Western phenomenon, the video game/anime/movie/card game/merchandise extravaganza that is and always was Pokemon being probably the best single example.
