Nielsen Shifts Local Metrics

摘要

Nielsen has decided to change the metric upon which advertising deals for local television ads are measured. In an effort to improve ratings for local broadcasts - which are often watched on digital video recorders minutes or days later - Nielsen wants to implement a "live-plus-same-day" measurement, which would account for viewers who watch either live or within 24 hours of air time.rnWhile national television has not suffered the same fate because it uses C3 rating, which measures the portion of ads viewers do not skip past, local networks are judged on program ratings.
