Way back in 1902, Columbia and RCA Victor were locked in a struggle to gain recording dominance of opera music. This was the highest prestige market, and recorded works commanded a premium, as the artists were very expensive to sign, and reluctant to put their voices out there for the general masses.
Victor named its offerings Red Seal, and charged twice as much as for other recordings. The product was, perhaps predictably, seldom a best-seller, although Enrico Caruso is credited with history’s first million selling record, again, in 1902. Victor did establish, with Red Seal, a bar for production excellence that lasted for the next century.
