Public Relations, Public Affairs, Public Diplomacy

Throughout this semester I have been trying to come up with my own definition for Public Relations, Public Affairs and Public Diplomacy. This is what I have come up with:

Public Relations is the relationship between a business and it's audience. This involves all communication between the two. Including, the way a business reacts to a crisis, handles an event or responds to consumer demand. Anything involved in communication between the business and it's audience is public relations.

Public Affairs is news that effects ourselves or our community, such as social responsibility. Something that we as people in a community would like to see accomplished or created. An example would might be a wanting to have a more green community, and any events or efforts towards creating a greener community would be considered public affairs. This definitely relates on a much larger scale, including not just communities, but towns, cities, states and even the country.

Public Diplomacy I see more as national or international efforts, and definitely more in involved in politics. Yes, public relations and public affairs are also largely apart of politics, but my perception of public diplomacy is that it is more based on decisions from political parties.

My perception is in public relations decisions are decided based on the business, in public affairs decisions are based on local or national politics depending on the situation, but public diplomacy is more based on decisions on a national and international political level.
