Filben Maestro 78 rpm jukebox
In the 1960s and 1970s, record companies released EP versions of long-play (LP) albums for use in jukeboxes. These were commonly known as "compact 33s" or "little LPs". They played at 331⁄3 rpm, were pressed on seven-inch vinyl and frequently had as many as six songs. What made them EP-like was that some songs were omitted for time purposes, and the tracks deemed the most popular were left on. Unlike most EPs before them, and most seven-inch vinyl in general (pre-1970s), these were issued in stereo.
