Nintendo has been selected as the world’s best company. A commitment to innovation, diversified portfolios, aggressive expansion, strong leadership and a clear vision for the future – these are just some of the strategies employed by the best companies to get to the top of the World’s Best Companies/Global Top 40 list compiled for Businessweek by management consulting firm A.T. Kearney. Two groups stand out: technology and telecommunications companies that have tapped into continuing demand for mobile phone service and new digital hardware and services, and heavy industry and engineering outfits benefiting from the uptick in infrastructure spending. It is also worth noting that neither Sony or Microsoft made the Top 40 list. The top three companies were Nintendo, Google and Apple, in that order.
