Bill Kerr tells a Credit Suisse Media Conference session (3/8) that he’ll meet with House Oversight Committee Chairman Edolphus Towns (D-NY) about Arbitron’s roster of proposed changes to the PPM system. Arbitron disclosed in a recent SEC filing that on February 12, it had suggested these possible changes: doing in-person recruiting of PPM panel members in the high-density black and Hispanic areas in the top 25 PPM markets by year-end. Going to address-based sampling in all 50 meter markets by 2011. Convening a minority leadership council. And conducting “advertiser outreach” on behalf of minority radio.
