This article argues that actors in different event networks experience different dynamics in terms of the joint organising of the event. The Political Market Square (PSQ) model is used to describe, analyse and compare the interactions and dynamics going on in three event networks. The purpose is to categorise different kinds of PSQs in terms of actors' interactions and network dynamics, which, in turn, contributes to knowledge on how events are produced using a network perspective. An analysis of the different event networks resulted in three different categories of Political Market Squares - the jungle, the park, and the garden, representing a tumultuous, a dynamic, and an institutionalised event network. The institutionalised PSQ (the park) is often prescribed in literature on event organising. Therefore, more research focused on understanding tumultuous and dynamic event networks (the jungle and the park) are needed. (C) 2008 Published by Elsevier Ltd.
