RCA 45 EP "Extended Play" Record Advertisement

RCA Records introduces the 45 RPM Extended Play record. An extended play (EP) is a vinyl record which contains more music than a single, generally twice as much music, but is too short to qualify as an LP.

EPs were introduced as compilations or samplers and typically played at 45 RPM. Some later releases were playable at 33 1/3 RPMs. The 33s were more common as special releases for jukeboxes and for common retail releases in various countries throughout the world.

Here is a very early advertisement introducing the extended play record.

RCA Records introduces the 45 RPM Extended Play record. "Twice as much music on ONE "45 EXTENDED PLAY" record!" Neat ad that I came across some years ago.
