Answer: institutional advertising
Explanation: Institutional advertisement, also known as corporate advertising, is any kind of advertising supporting a company, corporation, institution or similar entity.
The corporation is marketing itself rather than its brand in corporate advertising. The thing to keep in mind here, nevertheless, is that organizational marketing is not meant to specifically sell something.
Instead, it attempts at creating a business identity and building respect for the company and educating customers about the organization's ideology. It mostly tells the public at large about the institution's work in the fields of wellness, schooling, climate, and other similar fields and attempts to build the company's reputation.
