Millions of shoppers at Wal-Mart Supercenters and Bodega Aurrera locations in Mexico will see and hear about store products over the Bentonville, Ark.-based giant's retail media network, operated by Paris-based Thomson's Premier Retail Networks, Inc. (PRN). Wal-Mart said the change will enhance the existing in-store media network and deliver better-targeted media experiences to its shoppers where they make 75 percent of their purchase decisions.

Wal-Mart's is the largest in-store media network in Mexico.

The chain will use an end-to-end solution from PRN, including digital in-store media strategy, customized programming, advertising sales, and operations. The system features large plasma screens in select areas in the store and 19-inch flat-panel LCD screen at checkout lanes and waiting areas.

Two channels with displays drive the network with programs designed for specific store locations. The storewide channel tells shoppers about store products and encourages cross shopping. The waiting area channel lets shoppers watch content at checkout and in service areas to reduce perceived wait times. The in-store mix includes original content and content developed with partners and advertisers.
