Actually, what we see in many of the current reflections on new media is that while the spectator is being accused of ultimate passivity, he is also being mobilized to emancipated action as an empowered user. Through the critique of an online application available on Portuguese Radio Television （RTP）＇s website, the state-owned television network, called 0 Meu Telejornal1, we will try to demonstrate that we actually need to develop a spectator theory to critically understand the political position of the citizen within our changing contemporary media environment.展开更多
