Nielsen to Offer Fourth Set of DVR Data

Nielsen Media Research, which has previously announced it would provide three streams of ratings data in late December to deal with the lagging effects of DVR playback, has announced that it will add a fourth stream specifically for journalists who track the TV ratings system, Mediapost reports. The original plan was already complicated, and had buyers and sellers struggling to decide which set will be used as the currency of TV ad deals, particularly since they are beginning to plan for the 2007 uprfront advertising marketplace.
