Nielsen SocialGuide is now distributing the weekly measurement the Twitter TV Ratings Weekly Top Ten, and the measure for the week of Nov. 11-17 shows one series, AMC’s "The Walking Dead," holds a commanding lead in unique audience.
NBC’s "The Voice," however, is No. 1 in the total number of Tweets.
The shows are ranked by unique audience, where "Walking Dead" is a runaway No. 1 with 4.07 million, followed by "The Voice" at No. 2 with 2.50 million.
In number of tweets, "The Voice" is No. 1 with 595,000, well ahead of No. 2 "Walking Dead" at 262,300.
"Nielsen Twitter TV Ratings go beyond activity to measure the actual reach of Tweets about TV shows," Nielsen noted. "The ratings include not only ‘authors’ (the number of people tweeting about TV programs) and the total number of Tweets, but also the much larger ‘audience’ of people who actually view those Tweets."
Nielsen defines "unique audience" as "the total number of distinct Twitter accounts accruing at least one impression of one Tweet ascribed to a TV episode. Unique Audience is de-duplicated at the account level, so that a Twitter account will be counted only once for a given reported episode regardless of how many impressions the account accrued for that episode."
The measure captures relevant Tweets from three hours before, during and three hours after an episode’s initial broadcast, based on local time, Nielsen notes.
The company adds: "Unique Audience measures the audience of relevant Tweets ascribed to an episode from when the Tweets are sent until the end of the broadcast day at 5 a.m. The data includes new/live primetime and late fringe episodes only and excludes sports events. Nielsen Twitter TV Ratings are only available for English-language U.S. Broadcast and Cable Networks."
