In the United States, the disco craze of the late 1970s led to the release of extended "disco" versions of songs, most of which were released on 12" vinyl singles. Many of these were not easily beatmixed, so DJs started to laboriously edit songs by splicing reel-to-reel tape copies, making their own, unique versions that were better structured for a dancefloor. 1977 saw the creation of the first remix service, Disconet. These companies gathered DJs and producers together to create monthly, promotional-only compilation albums containing re-edits, remixes, or medleys that were geared specifically toward club DJs.
