Stichting CPG stands for Stichting Collectieve Promotie Geluidsdragers, which is a cooperation of the Dutch record stores, record companies and the copyright organisation Buma/Stemra.
Since 2003 their activities have been taken over by STEP (Stichting Entertainmentretail Promotion), an initiative of NVGD (Nederlandse Vereniging van Grammofoonplaten Detailhandelaren).
