That's when it fully integrates data garnered from satellite provider Dish Network into its system. The data will power both its national and local-market ratings products as it looks to trump Nielsen with ratings from more homes nationally and provide commercial ratings locally. While most of the estimated 17 million homes will be served by Dish, data from AT&T U-verse (telco TV) and Charter Communications (cable) will be melded in for the full universe. Both Rentrak's TV Essentials (national) and StationView Essentials (local) services offer second-by-second data, including commercial ratings, but only at the household level. There are no demographic breakdowns.
