The origins: the birth of the single
The 45 RPM vinyl single arrived in 1949, introduced by RCA Victor as a compact alternative to the brittle shellac 78. Where the LP was built for the full album, the 45 was built for the single song.
Its small size, large centre hole and quick playtime made it perfect for jukeboxes and for the growing business of selling individual hits to a young audience.
