History The Domino's Pizza company was founded in 1960, by American entrepreneur Tom Monaghan as a single pizzeria in Ypsilanti, Michigan. The first store in the UK opened in Luton in 1985. The master franchise for the British Isles was sold off by the parent company in 1993 to Domino's Pizza Group, a subsidiary of the International Franchise Systems holding company controlled by sibling investors Colin and Gerry Halpern. The company partially floated its shares on London's Alternative Investment Market in October 1999, by which time it had expanded to a network of almost 200 branches (of which all but eight were franchises). Certain investors such as Colin Halpern and property entrepreneur Nigel Wray retained significant stakes at this time. The company opened its 400th store in Wadsley Bridge, Sheffield in November 2005. The 500th store opened in the end of 2007, in Hatfield, with the 600th following in December 2009, in High Holborn, Central London, being opened by Stavros Flatley. The Domino's share transferred from AIM to the main market of the London Stock Exchange in May 2008, and was promptly added to the FTSE 250 Index at the next quarterly review the following month.
