Internal PR manages relationships with internal stakeholders like employees, shareholders, and family members. It aims to provide them with relevant updates, recognition, motivation, and a sense of community. External PR focuses on clients, customers, the media and the general public. It coordinates with journalists to maximize positive coverage and maintains important relationships with customers through communication, marketing research, and ensuring their value, cost, and convenience. Financial information shared with shareholders should be explained through text and numbers, with fair treatment and respect.
