An article in the New York Times (October 26,2012) describes same day delivery offered by Google in San Francisco. The company coordinates with retailers to deliver products ordered following Google searches. Linking the search with purchase and physical delivery closes the customer loop for the retailer, and ensures that the retailer understands the value of the Google search ad. But will same day delivery is a threat to stores who ensure customer demand is satisfied, and may thus drive down revenues ? But will Google be able to guarantee delivery without control of inventory, as Amazon does ? And will truck routes that deliver following optimal routes decrease the environmental impact of shopping ?
