Nielsen’s Ratings Problem Is A Total Glitch (LostRemote)
Nielsen Friday announced internal “ratings irregularities” that date back to March 2, 2014 and were “generally imperceptible until [the company] saw high viewing levels associated with fall season premiere week.” TVNewser The company will now reprocess all of the impacted data going back at least to Aug. 18 — for entertainment, news and syndicated shows. TVNewser The company Saturday released updated data for the week of Sept. 22, which was the first week of 2014-15 TV season. As suspected, the inaccurate data favored ABC programs while hurting ABC’s competitors. The restated numbers are being most closely watched for revisions to the primetime ratings as new fall shows had their premieres. In the tight evening news race, World News Tonight With David Muir, had its numbers revised down, but it didn’t change the outcome. Muir’s newscast still won the week in the demo, and NBC Nightly News With Brian Williams won among total viewers. HuffPost Nielsen, the leading global measurement company and provider of television ratings data, said in a press release Friday that “a technical error” resulted in incorrect data over the course of about seven months. WSJ The difference in what was misattributed was less than 0.05 of a ratings point for about 98 percent to 99 percent of broadcast and syndicated TV shows, Nielsen said. The error didn’t affect overall TV viewership numbers, only how that viewership was credited to particular networks. Cable TV ratings weren’t affected by the glitch, it said.
