SocialGuide has launched a daily rating of the top programs, networks and sporting events based on the social media activity that takes places while the show is airing. The Brooklyn, N.Y. based tech start-up had been offering monthly and weekly rankings of the top shows and networks for May and June, and the launch of daily rankings is part of their effort to expand coverage of the social activity around TV shows, reports Broadcasting & Cable. SocialGuide tracks Twitter feeds one hour before and two hours after the program airs but the rankings are based only on the activity that is going on during the show because that period is the most important for networks and sponsors in terms of advertising revenue.
