It was not clear at press time whether the enhanced weighting process has been audited or accredited by the Media Rating Council.
In a second announcement, Nielsen unveiled the schedule for consolidating its various national ratings data systems to a single "calculation platform" over the next two years. The new platform will take services utilizing two different systems--pre-aggregated, quarter-hour data products such as Galaxy Explorer, MIT files, market breaks, and most of Nielsen's published reports; and individual minute, person-by-person data products such as Npower and the average commercial minute MIT file--and put them on a single platform providing consistent estimates across all products and reports.
Nielsen said moving to a single platform would enable it to modify its products and data streams much more rapidly, and that the move would make it easier to integrate audience data from non-traditional sources such as the Internet, mobile devices and digital set-top devices.
