With community relations, a company takes an active interest in the community/communities it serves. This can be achieved, for example by a business attending grand openings or milestone events for local businesses or through sponsorship/promotional partnerships. 

Community relations build relationships with the local communities you serve, providing positive visibility to your organization and to your brand. By focusing on these local communities, your company can greatly impact a vital local market and develop lasting ties along the way. Robert Morris University in Pittsburgh, Pennsylvania, offered classes to members of the community by allowing them to register for one class in any discipline, which increased the number of applications for admission from local-area students.
