Nielsen released its first ever Twitter ratings on Monday, providing TV networks a new measure by which to pitch their shows to advertisers.
The Nielsen Twitter TV ratings, based on data provided by Twitter, measure the number of tweets about a show and the size of the audience that sees those tweets, the Wall Street Journal reports. Breaking Bad was No. 1 for the first report, covering the week of Sept. 23, with 9.3 million unique users seeing tweets about the show.
That’s a far different measurement than audience size; Breaking Bad was just the sixth-highest rated TV show in terms of number of viewers during that same week in the key demographic of 18- to 49-year-olds. Other most-watched shows, like The Big Bang Theory and NCIS, didn’t even make the top 10 on the Twitter TV ratings.
