Mobile marketing blog

The Brazilian equivalent of Amazon.com, Editoras online, built a very effective strategy using Mobile Marketing in the form of QR codes.

Their employees placed 4000 QR codes at key locations throughout Sao Paola. When people used their mobile handsets to take a picture of the image (including the QR codes) their mobile handset were directed to a strategic selection of Twitter mini blogs they affectionately refer to as their "living book". Each tweet contained a viral call to action leading the reader to their Editoras on-line website.

Their ROI was massive and added to their brand reputation. The full details of their campaign an be seen in this video - http://www.youtube.com/watch?v=PG4thXVM2qk.
