Explanation:

An interest group is a group of people, organized around a common interest, in order to act jointly in defense of it. It is called a pressure group when that group seeks to influence public opinion. Its political activity is distinctive of other categories because they try to intervene in the political subject from outside of this, that is, indirectly. Often interest groups are public knowledge, such as trade unions, employers' organizations, large companies, professional associations, NGOs, etc.
