This study analyzes the register of television sports announcers in Major League Soccer broadcasts, based on six 20-minute transcription samples. The first part considers individual linguistic features and inquires whether they fulfill a communicative function or whether they are of stylistic nature. In an effort to attract more viewers in the United States, production companies had originally adopted the duality model of a play-by-play announcer and a color commentary from other American sports, while many other countries traditionally feature only one commentator. Consequently, the second part of this discourse analysis will focus on the cooperative interactional behavior. The conclusion will be drawn that the register of live action announcing, in contrast to halftime as well as pre- and post-game reporting, is based on cooperative principles. Moreover, both the individual and the collaborative linguistic variables mostly reflect an effort to protect one’s own and the colleague’s public image.
