Issue networks are an alliance of various interest groups and individuals who unite in order to promote a common cause or agenda in a way that influences government policy. Issue networks can be either domestic or international in scope depending on their collective goal. With the rise of the internet, many interest groups have turned to online resources, such as blogs and social media, to promote and spread their cause because of its low cost and high efficiency in outreach. An Issue network's tactics vary depending on their goals and purpose. In developed countries, issue networks often push for a change in policy within the government bureaucracy. An example includes the wide-ranging network of environmental groups and individuals who push for more environmental regulation in government policy. Other issue networks may revolve around such controversial issues as abortion, gun ownership rights, and drug laws. In the most extreme circumstances issue networks may seek to achieve their means through violence, such as terrorist organizations looking to overthrow existing governments all together. In the U.S, the most common tactic of effective issue networks is the role they play in what is called Iron Triangles. This is the term used to describe the three way back and forth communication process between Congress, Bureaucracies, and the interest groups that make up an issue network where they discuss policy and agendas in order to compromise on solutions to satisfy each other's goals.

Iron triangles are three-pronged relationships that are used between interest groups. Generally these interest groups are composed of businesses, congressional committees, and Federal agencies set to deal with a certain issue. These iron triangles do not have the general welfare of the public in mind, but are for the furthering of favorable policies for the interest group. For example, an iron triangle dealing with fossil fuels would be composed of a business or corporation dealing in fossil fuels, a congressional committee who oversees fossil fuel laws and regulations, and a fossil fuel Federal Agency which makes sure these laws are obeyed. However, iron triangles do not benefit the public, they only benefit the players within the iron triangle. Some cases these iron triangles not only benefit inside the ring, but often do so at the expense of the constituencies that Congress and these Federal bureaucracy’s are supposed to represent.
