Tadacopy: ads in unexpected places

Springwise showcases Tadacopy, a Japanese company that is selling ad space on the backs of photocopies (or rather, photocopies-to-be). Students who use the blank sides of the ads to make photocopies are not charged for the copying. The paper is slightly thicker than everyday paper so that the ads don't shine through, and advertisers are able to reach their target audience in yet another way.
