In this paper, we investigate a new style for presenting information. We introduce the motion of presentation teams which — rather than addressing the user directly — convey information in the style of performances to be observed by him or her. The paper presents an approach to the automated generation of performances which has been tested in two different application scenarios, car sales dialogues and soccer commentary.
