In 1986, Sampson Tyrrell was acquired by the WPP Group plc. This resulted in a period of rapid growth and by 1991 the company was over 100 people in London. In 1992 Sampson and Allen led the formation of Enterprise identity Group with Jim Johnson of Anspach Grossman Portugal, Flavio Gomez of Sidjakov Berman Gomez and Miles Young of Ogilvy and Mather in Asia who owned a design network based in Hong Kong and Taiwan called Artistree. This was in response to the needs of international brand owners who were rapidly globalising the brands and their businesses around the world. Most particularly in Asia. All the founding businesses were formally transitioned into a new brand - Enterprise IG. Enterprise IG was formally launched in 1996. At this time and Allen and Johnson became Joint CEOs.
