Core-stores panel updated.

In the Feb. 11 edition of Billboard Magazine, Nielsen SoundScan and Billboard complete an update of the core-stores panel that govern the magazine’s R&B/hip-hop sales charts.

Stores on the panel carry a broader than average inventory of titles from those genres and are located in markets that include at least one currents-based station from relevant radio formats.

Revised by Billboard chart manager Raphael George and Chris Muratore, director of retail relations and research services for Nielsen Entertainment, the panel grows to 1,263 independent, chain and mass merchant stores from 966 in the revamp of November 2004.
