Companies today understand that corporate social responsibility (CSR) forms an inextricable part of their reputations and brand identities. They spend ever-increasing amounts of corporate resources on improving the social, human, and environmental conditions under which companies operate. Yet the world's problems seem as intractable as ever, and very few global companies have managed to rise above the public relations din to truly distinguish themselves through their CSR activities. One of the primary reasons CSR has not yet significantly improved society is that the nonprofit and business sectors are for the most part still stuck in their old stereotypical roles. By ceding responsibility for solving social problems to nonprofits, companies have forsaken their ability to intervene directly in healing the world's woes. As a result, some of the most sophisticated and powerful organizations in the world remain on the sidelines of social progress. Companies that get into the game and play to win will reap disproportionate social impact, economic rewards, and reputational benefits.
