NYT: Arbitron delays new rating system that more accurately counted radio listeners to the chagrin of Univision.

Arbitron delayed the rollout of a new more accurate system that showed lower numbers for ethnic radio stations. Univision was relieved.

“Our real concern has not been the tool itself, but the sample and the compliance measures,” said Ceril Shagrin, an executive vice president for corporate research at Univision Communications, a major Spanish-language broadcaster, echoing concerns that young listeners and ethnic groups are not adequately represented in the meter ratings.
