Arbitron to expand PPM trial


Arbitron Inc. said Wednesday that it will expand its "Portable People Meter" trial in the United States.

The company plans to equip a new and separate panel of approximately 1,000
consumers in the Philadelphia Radio Metro Survey Area that will allow direct
comparisons to the radio-station-audience estimates being produced by the
existing panel of consumers in the current PPM market trial.

Arbitron also said it agreed to consider a request from clients for a second
PPM market trial in one of the top 25 Hispanic markets. But
the company added that fielding this second PPM trial market would be contingent
on the formation of a proposed joint venture with Nielsen Media Research,
which the latter is currently mulling.
