Abstract
The aim of this paper is to uncover the system of actors who have shaped the environment of Czech documentary film and its transformation over the last ten years. These are major institutions such as television, The Czech Film Fund, festivals and institutions dedicated to the education of film profes-sionals.
The ecological perspective gives insight into individual aspects as well as the overall system. From this perspective, different parallels with life, relationships and sustainability in nature are emerging, which are becoming a tool for analyzing relationships in the media world.
The ecosystem study of documentary film institutions relies on research into the environment through individual actors that are active in the system, are involved in a network of collaborative and exploitation rela-tionships, provide direct insight into the environment and can determine its specificities and cap-ture transformations (directors, producers, television or educational platforms).
