Wal-Mart stepping up in-store marketing experiments

This isn't excatly digital signage news per se, but considering that Wal-Mart has one of the largest and most heavily-touted in-store TV networks around, it seems fitting to mention their ongoing activities with at-retail marketing.

MSNBC is carrying an interesting article about Wal-Mart and their in-store agency of record, Saatchi X. Apparently the retailer is experimenting with a number of new strategies that involve everything from reorganizing the store layout to giving away free WiFi access, all in an attempt to let customers spend more time shopping, and less time just searching for products.

I don't have anything to add to this just yet, but thought it might be worth passing along.
