CSR is an acronym which stands for "corporate social responsibility". In simple terms, this is the responsibility for a company to uphold certain social ideals and promote honest and upfront products and services. One big way that the future of CSR is changing is that CSR is actually now kind of evolving into a similar, but yet very different, idea called "corporate social impact".
Basically, the different is asking "what can my company change in our society" rather than "how can my company change to fit social constructs". This is a pretty big difference and leads to better business branding and ethics. It challenges CSR/CSI developers to pay attention to the ads, products and services they are providing.
