The Importance of the Sports and Entertainment Industry World class cities are known for having a number of sought-after attributes, including those that attract and retain a diverse workforce, provide a wide range of cultural experiences and offer a strong base of amenities and experiences for locals and visitors. For the past decade, A.T. Kearny, an international consultancy, has produced rankings of “global” cities. To provide some perspective, the top global cities include New York, London, Paris, Tokyo, Hong Kong and Los Angeles. While the order of world-class cities may change from year to year, they all tend to rank high in terms of business activity, human capital, information exchange, cultural experiences and political engagement.
