QUESTION: What is the biggest franchise group in the world in terms of its number of sites or outlets?
CLUES: (1) It is a franchise group, ie it owns more than one brand. (2) Its sites are restaurants, there's 36,000 of them in more than 110 countries. (3) It had total revenues in 2008 of US$11 billion (A$15.3 billion). That includes revenues in Australia of A$1.5 billion. (4) It is the world's second biggest franchise group in terms of market capitalisation, after McDonald's. So it's not McDonald's.
ANSWER: The group is the owner of KFC and Pizza Hut, both operating in Australia. Of the 36,000 sites mentioned above, 14,000 are KFC outlets. The group also owns Taco Bell, A&W and Long John Silvers - all untried or unsuccessful in Australia. With all these brands, this is why it is a franchise group. The group is the United States-based YUM! Brands - http://www.yum.com.
