local firms. Arthur Andersen was the exception: the firm originated in the United States, and then expanded internationally by establishing its own offices in other markets, including the United Kingdom. Price Waterhouse was a UK firm which opened a US office in 1890, and later established a separate US partnership. The UK and US Peat Marwick Mitchell firms adopted a common name in 1925. Other firms used separate names for domestic business, and did not adopt common names until much later. For instance, Touche Ross was named such in 1960, Arthur Young, McLelland, Moores & Co in 1968, Coopers & Lybrand in 1973, Deloitte Haskins & Sells in 1978 and Ernst & Whinney in 1979. Even now, Deloitte's legal name is Deloitte Touche Tohmatsu Limited, which reflects its history of mergers. In the 1980s the Big Eight, each with global branding, adopted modern marketing and grew rapidly. They merged with many smaller firms. KPMG was the result of one of the largest of these mergers. In 1987, Peat Marwick merged with the Klynveld Main Goerdeler group to become KPMG Peat Marwick, later known simply as KPMG. Note that this was not the result of a merger between any of the Big Eight. Big Six Competition among these firms intensified, and the Big Eight became the Big Six in 1989. In that year, Ernst & Whinney merged with Arthur Young to form Ernst & Young in June, and Deloitte, Haskins & Sells merged with Touche Ross to form Deloitte & Touche in August. The Big Six after both mergers occurred were: Arthur Andersen Coopers & Lybrand Deloitte & Touche Ernst & Young KPMG Price Waterhouse There has been some merging of ancestor firms, in some localities, which would aggregate brands belonging to the Big Four today, but in different combinations than the present-day names would otherwise suggest. For example, the United Kingdom local firm of Deloitte, Haskins & Sells merged instead with the United Kingdom firm of Coopers & Lybrand. The resulting firm was called Coopers & Lybrand Deloitte, and the local firm of Touche Ross kept its original name. It wasn't until the mid-1990s that both UK firms changed their names to match those of their respective international organizations. Meanwhile, in Australia, the local firm of Touche Ross merged instead with KPMG. It is for these reasons that the Deloitte & Touche international organization was known as DRT International (later
