臺灣媒體問題近年來備受社會批評，促成許多公民團體投入媒體的結構改革運動。透過簡要介紹2009年底的動新聞事件，以及2012年中的反媒體壟斷運動的過程與特點，本文認為近十年來這兩次重要的媒體改革倡議與實踐，顯示媒改運動的行動者及社會連結已有明顯擴大；但仍受限於政治與資本力量的夾擊，有待更為深化的公民參與，以突破困境並伸張公民的傳播權利。

In recent years the media in Taiwan have been subject to much criticism as well as civic engagement in campaigns for media reform. Through a brief review and analysis of the development of two social movements focusing on media issues-the News-in-Motion incident at the end of 2009 and the campaign against media monopoly in 2012, this paper argues that both the base of mobilization and the scope of social connection for media activism have been broadened. Nevertheless, the strengthening of civic engagement is necessary for media reform because the effects of media activism are still limited due to hostility from holders of political and business power.
