Nielsen 'Restates' TV Ratings

Following its admission last month of a flaw in the measurement of web traffic due to pages with 'very long URLs', Nielsen has now notified clients that it will 'restate' ratings for nine TV stations in four of its metered markets due to problems with 'software logic'.

Nielsen says the problem will not impact on November's crucial period for local TV advertising sales.

All nine stations are 'parent + satellite' meaning they are local stations which rebroadcast the signal from another station. Nielsen's policy is to report the combined audiences of those stations as a single entity. All the stations are based in Albuquerque, Austin, Birmingham and Indianapolis.

Nielsen has not explained the cause of the fault, but says it detected it when comparing data for the stations across different sources.

'The 'overnight' household ratings for these stations and all reported ratings for all other stations in these markets were not impacted', Nielsen said.

Last month's web traffic flaw related to URLs of more than 2,000 characters, often found on social media sites.
