“Corporate Social Responsibility” emerged in the 1990s as a new buzz in the business world, and since then has developed into a field with substantial and diverse career opportunities. The term ‘corporate social responsibility’ or CSR has been coined to define how companies behave in social, environmental and ethical contexts. Corporate social responsibility is about integrating the issues of the workplace, the community and the marketplace into core business strategies. Social enterprise is related to CSR through socially responsible business development. Social entrepreneurship can include social purpose business ventures, such as for-profit community development banks, and hybrid organizations mixing not-for-profit and for-profit elements, such as homeless shelters that start businesses to train and employ their residents. The new language helps to broaden the playing field. Social entrepreneurs look for the most effective methods of serving their social missions.
