advocacy group

Advocacy groups, also known as lobby groups, interest groups, special interest groups, pressure groups, public associations, government relations firms, or lobbying firms and in some cases public affirms firms, use various forms of advocacy or lobbying to influence public opinion and ultimately public policy. They play an important role in the development of political and social systems.

Motives for action may be based on political, economic, religious, moral, commercial or common good-based positions. Groups use varied methods to try to achieve their aims, including lobbying, media campaigns, awareness raising publicity stunts, polls, research, and policy briefings. Some groups are supported or backed by powerful business or political interests and exert considerable influence on the political process, while others have few or no such resources.
