The Americans at the time used the term to describe those music styles that they never heard before. It was the new beat of the time, the new sound, very different from Hi-NRG disco, New Wave, Synth Pop, Rap or whatever. The term was soon replaced by other terms, so virtually any USA hits once described as "New Beat" are today considered a part of another music style, most of the time simply House or Techno.
First, appeared in Belgium, around 1987, to describe a local music style that mainly developed out of 'Bodybeat' heralded by the early formation of Front 242.When MTV Europe began in the summer of 1987, it brought the term to the UK. In the UK, the term New Beat was used in 19871988 for various local Acid House / Techno Rave productions, to point out that this was a new sound of dance music and a less commercial alternative to UK's Eurobeat. Eurobeat was at the time used in the UK for the Stock Aitken Waterman productions.Eventually, the term became mainstream, especially between the summer of 1989 and the summer of 1990, but faded fast after Euro House took over.Because of the relation of the "New Beat" and Acid House in the UK during 1988, the later commercial "New Beat" European productions, sported the Smiley as symbol of love in the British related markets. Various British "New Beat" productions, eventually migrated to the 'Bacalao' scene in Valencia Spain.
Those groups are among the very few New Beat ones, that produced Music Videos and during the late 80s, they had a heavy airplay on the original MTV Europe, through the show "Party Zone". MTV Europe's VJ Steve Blame was a great fan of New Beat and through his position on MTV News, promoted the Belgium's New Beat sound through his reports.
New Beat incorporated more techno and acid house influences. Euro House had Euro Disco influences and for sure is not a New Beat / "Euro Disco" crossover. So for them, "Euro Beat" was a music style, that faded in 1990, for unknown reasons.
