Attention shoppers: digital ad screens are about to be everywhere you look

Amazon has specific rules about what types of ads can be shown on the screens at Whole Foods. Dominick Reuter/Business Insider Retailers have gradually added digital display ads to their stores for the past year. Now the pace is picking up as the concept gains wider acceptance with Walmart and Walgreens. A survey this year found that shoppers' acceptance of ad screens depends on the in-store context. Trips to the store used to offer a break from the digital screens that dominate modern life. Those days are winding down .
