In the late 1990's there was a growing realisation that for many 'post industrial' economies and especially the UK, not only had they become dominated by traditional 'service' businesses (banking, finance, retail, logistics, law and other professional service firms) but that the most rapidly growing group of these 'knowledge based' firms were in an ill defined sector that depended on creativity for their source of competitive advantage such as fashion, design, architecture, advertising and pr, books, music, film and tv production, theatre, online communities, video games, museum and gallery exhibitions and other print and screen based media.
