A reply from the list server's system administrator and founder of Brian Behlendorf, revealed that Parry originally wanted to create a list devoted to discussion of the music on the Rephlex label, but they decided together to expand its charter to include music similar to what was on Rephlex or that was in different genres but which had been made with similar approaches. The first message, sent on 1 August 1993, was entitled "Can Dumb People Enjoy IDM, Too?". Wider public use of such terms on the Internet came in August 1993, when Alan Parry announced the existence of a new electronic mailing list for discussion of "intelligent" dance music: the "Intelligent Dance Music list", or "IDM List" for short. And in July 1993, in his review of an ethno-dance compilation for NME, Ben Willmott replaced techno with dance music, writing ".current 'intelligent' dance music owes much more to Eastern mantra-like repetition and neo-ambient instrumentation than the disco era which preceded the advent of acid and techno." Another instance of the phrase appeared on Usenet in April 1993 in reference to The Black Dog's album Bytes. and UK music press in late 1992, in reference to Jam & Spoon's Tales from a Danceographic Ocean and the music of The Future Sound of London. Off the Internet, the same phrase appeared in both the U.S. In November 1991, the phrase "intelligent techno" appeared on Usenet in reference to Coil's The Snow EP. In 1993, a number of new "intelligent techno"/"electronica" record labels emerged, including New Electronica, Mille Plateaux, and Ferox Records. Rave had become a "dirty word", so as an alternative, it was common for London nightclubs to advertise that they were playing "intelligent" or "pure" techno, appealing to a "discerning" crowd that considered the hardcore sound to be too commercial. At the same time, the UK market was saturated with increasingly frenetic breakbeat and sample-laden hardcore techno records that quickly became formulaic. In the same period (1992–93), other names were also used, such as "art techno", "armchair techno", and " electronica", but all were attempts to describe an emerging offshoot of electronic dance music that was being enjoyed by the "sedentary and stay at home". Following the success of the Artificial Intelligence series, " intelligent techno" became the favoured term, although ambient-without a qualifying house or techno suffix, but still referring to a hybrid form-was a common synonym. Steve Beckett, co-owner of Warp, has said the electronic music that the label was releasing then was targeting a post- club, home-listening audience. This would help establish the ambient techno sound of the early 1990s. Subtitled "electronic listening music from Warp", the record was a collection of tracks from artists such as Autechre, B12, Black Dog Productions, Aphex Twin and The Orb, under various aliases. In 1992, Warp released Artificial Intelligence, the first album in the Artificial Intelligence series.

By the early 1990s, the increasingly distinct music associated with dance music experimentation had gained prominence with releases on a variety of mostly UK-based record labels, including Warp (1989), Black Dog Productions (1989), R&S Records (1989), Carl Craig's Planet E, Rising High Records (1991), Richard James's Rephlex Records (1991), Kirk Degiorgio's Applied Rhythmic Technology (1991), Eevo Lute Muzique (1991), General Production Recordings (1989), Soma Quality Recordings (1991), Peacefrog Records (1991), and Metamorphic Recordings (1992). In the late 1980s, riding the wave of the acid house and early rave party scenes, UK-based groups such as The Orb and The KLF produced ambient house, a genre that fused house music (particularly acid house) with ambient music. In 2014, music critic Sasha Frere-Jones observed that the term "is widely reviled but still commonly used". The term has been widely criticised and dismissed by most artists associated with it, including Aphex Twin, Autechre, and μ-Ziq. The term "intelligent dance music" was likely inspired by the 1992 Warp compilation Artificial Intelligence and is said to have originated in the US in 1993 with the formation of the "IDM list", an electronic mailing list originally chartered for the discussion of English artists appearing on the compilation.

Prominent artists associated with it include Aphex Twin, Autechre, Squarepusher, Venetian Snares, Boards of Canada, μ-Ziq, the Black Dog, the Future Sound of London, and Luke Vibert.

It emerged from the culture and sound palette of electronic and rave music styles such as ambient techno, acid house, Detroit techno and breakbeat it has been regarded as better suited to home listening than dancing.

Intelligent dance music (commonly abbreviated as IDM) is a style of electronic music originating in the early 1990s, defined by idiosyncratic experimentation rather than specific genre constraints.
