NBC Universal  and Google entered into a multi-year partnership in which Google will broker TV advertising on some NBC cable channels. The deal, set to go into effect in coming months, covers advertising inventory through Google TV Ads service on Sci Fi, Oxygen, MSNBC, CNBC, Sleuth, and Chiller, and maybe more. Google and NBC will split the revenue and collaborate on marketing and research. The Google TV Ads service can report second-by-second TV usage data allowing more precise measurement of ad viewership. For NBC, this pact is a way to target ads at specific audiences and attract new advertisers.
