Due to technical issues in the record playback process, the practice of creating separate mono and stereo mixes of the same record was common during the 1960s. This also required manufacturing and distributing mono and stereo versions of the same album title. The Haeco-CSG system appeared to be an attractive option for record companies and retailers by allowing them to cut costs. Engineers could produce a single mix, record companies could manufacture and distribute one version, and vendors could stock one product.
