When CDs began to appear as a popular single format in the early 1990s (see
CD single), songs were occasionally released in two CD formats simultaneously, 3" and 5", predominantly as a marketing ploy but potentially as a logical extension of the 7" and 12" vinyl record formats to CD, with the 5" CD sometimes marketed as a "maxi-single", most commonly in the US, and European countries (outside of the UK). While the 5" CD version occasionally had additional or longer track mixes, the track listing was often identical. By the mid 1990s CDs had clearly become the music format of choice. As the 1990s progressed, nearly every single release was available on CD, and vinyl and cassette single releases gradually became less common. The UK became a thriving market for CD singles, but in 1998 the UK Chart Supervisory Committee reduced the maximal playing time of chart-eligible CD singles from 40 minutes to 20 minutes, though 12" vinyl singles could still play for up to 40 minutes. While Maxi-CDs had been much loved among the dance community, as most if not all of the remixes that had been commissioned by the label could be released commercially, lobbying by artists in other genres who felt obliged to record extra and cover tracks to provide enough material for their single releases was responsible for the rule change. As a result, the U.K.'s singles from around mid-1998 often appeared as three separately-sold CDs with three tracks each, or more commonly, two CDs and an extra format (such as 7", 12" or DVD single). Very often, at least one track was common to all formats. Single releases in the US and elsewhere still included many tracks (primarily remixes) and called themselves maxi-singles to differentiate from the three-track UK versions. Example:
Saint Etienne "Who Do You Think You Are?" (US CD single) Released by Warner Music in 1993 in the US. Includes eight different tracks, six of which are versions of the title song.
Digipak packaging. Labeled "compact disc maxi-single" on the front cover. Another extensive example is the collection of singles released for the award-winning
Mellon Collie and the Infinite Sadness by
The Smashing Pumpkins. Each of the five singles ("
Bullet with Butterfly Wings", "
1979", "
Zero", "
Tonight, Tonight", "
Thirty-Three") had two or more additional songs; most of them had six or seven. All of the maxi singles were released together, with additional tracks on some, as
The Aeroplane Flies High box set, for a total of thirty-three tracks across the five singles. Adding that to the total number of other unique tracks on the main CD and vinyl releases of the album itself brings the grand total track count of
Mellon Collie to fifty-eight. As a result of the 1998 UK Chart Supervisory Committee ruling on chart-eligible singles containing no more than 20 minutes of material, many of the U.K.'s dance music singles contained edited / faded mixes. This increased demand for imported European & American CD maxi singles in the UK, especially amongst DJs who required full-length tracks. ==Digital maxi singles==
