NEW YORK — ABC has notified the A.C. Nielsen Co. that it wants to end its agreement with the ratings company effective Aug. 31, just before the beginning of the new television season, the network said Friday.
The third-ranked network's announcement came just as the ratings service reported that it was set to change its way of measuring a show's popularity. A prepared statement from ABC, however, said that the decision was made independent of Nielsen's new plans.
The Nielsen company uses an audiometer, which is attached to the back of television sets, but soon will install People Meters, a system in which viewers push buttons to record what they watch.
CBS said it did not object to the system, but NBC and ABC had said it should be given more study.
