Walmart to Roll Out 'Smart Network'

Mediaweek: "Rolling out in time for the holiday season to about 300 stores, the Walmart Smart Network will be powered by Internet Protocol Television, allowing content and advertising to be monitored and controlled down to a single screen. By 2010, Walmart anticipates chain-wide deployment of 27,000 screens by early 2010.

Initially, advertisers (limited to those companies with products in the store), will be required to buy across the entire network of stores. As the network rolls out, advertisers will be able to target more precisely by store, by screen, by day and by time-of-day, as well as change messages daily."
