A period of significant growth in the early 1980s was driven by demand for strategy and organization consultancies. The wave of growth in the 1990s was driven by both strategy and information technology advice. In the second half of the 1980s, the big accounting firms entered the IT consulting segment. The then Big Eight, now Big Four, accounting firms (PricewaterhouseCoopers; KPMG; Ernst & Young; Deloitte Touche Tohmatsu) had always offered advice in addition to their traditional services, but after the late 1980s these activities became increasingly important in relation to the maturing market of accounting and auditing. By the mid-1990s these firms had outgrown those service providers focusing on corporate strategy and organization. While three of the Big Four legally divided the different service lines after the Enron scandals and the ensuing breakdown of Arthur Andersen, they are now back in the consulting business. In 2000, Andersen Consulting broke off from Arthur Andersen and announced their new name: Accenture. The name change was effective starting January 1, 2001 and Accenture is currently the largest consulting firms in the world in employee headcount. They are publicly traded on the NYSE with ticker ACN.
