Nielsen TV Diary-Only Ratings Lose MRC Accreditation

Dear Diary...

NIELSEN's ratings measurement of 154 diary-only television markets has lost its accreditation by the MEDIA RATING COUNCIL. Larger markets with metered ratings are unaffected.

BROADCASTING AND CABLE cites "insiders" saying that the problem leading to the loss of accreditation came from sample issues arising from NIELSEN's use of address-based recruiting rather than the old phone-number system in an attempt to address the issue of cell-phone-only households. NIELSEN has requested a new audit and says that the issues have been worked out.
