Arbitron Axes Arbitrends, Diaries in Philly; PPM a Go

Arbitron has announced that all ratings in Philadelphia produced with pencil-and-paper diaries will end with the release of the fall 2006 survey on Jan. 11.

The fall 2006 diary-based ratings report will remain the currency in the market until the release of the March 2007 PPM ratings report. In the meantime, the January 2007 and February 2007 PPM radio ratings reports will be released as demonstration data, Arbitron says.
The Arbitrends report will no longer be published for Philadelphia. Instead of Winter Phase 1 and 2 Arbitrends reports, subscribing stations will receive monthly PPM-based audience estimates using the installed PPM sample, which is planned to be 2,040 persons, age 6 and older.
The first PPM monthly audience estimates are scheduled to release on February 28 for the monthly survey of January 11 to February 7.

PPM subscribers should receive the electronic ratings 21 days after the end of each monthly survey, including a Holiday Survey for listening between December 13, 2007 and January 9, 2008.

The monthly PPM ratings for Philadelphia will be available in three different formats:

• PPM e-book - the Radio Market Report delivered electronically (first delivered February 28 for the monthly survey of January 11 to February 7);
• Summary-level data, including ethnic reports - released to licensed third-party software providers that have prepared their applications for the PPM data (first delivered February 28 for the monthly survey of January 11 to February 7);
• Respondent-level data - for use in the PPM Analysis Tool software (first delivered March 28 for the monthly survey of February 8 to March 7 and will include the January survey as back data).
