I just found photographies of McGill metro station from Montreal, and I must say I really dislike the colors. Since the start of march the station is covered with iPod ads… and in a heavy manner. It seems all the stations of Paris (in french) suffer from the same thing too.
Not that I dislike the iPod, but these ads are a lot too much intrusive to my taste: there is too much of them. There is less advertisement even inside a McDonald’s! I really hope no one get inspired by this.
