This paper tracks the growth and decline of information and communications technology (ICT) industries that were synonymous with the so-called new economy boom of the late-1990s and its subsequent bust period in the early 2000s. The analysis focuses on the question of whether the ICT bust has been accompanied by a structural shift illustrated by less firm turnover. It shows that to date there is little evidence of a structural shift. Entry rates of new establishments within the ICT sector were above those of other sectors within the economy during both the ICT boom and bust.
