The purpose of this research is to study the genre television advertisements and verbal interactions under Bakhtin`s perspective. The main corpus of the study is composed of data from TV ads, having been recorded and transcribed 11 samples of Brazilian car advertisements of FIAT Automobile Company, produced from 2000 to 2003. The analysis of the ads was based on theoretical concepts extracted from Bakhtin`s language theory (1981, 1992 and 1997), considering genre, verbal interaction, dialogism, discursive voices, intertextuality and irony. Based on the results of the analysis, the classification of television advertisements as a complex intersemiotic genre is proposed. Data analysis also led into the characterization of TV ads as a fusion of the advertisement genre itself together with its supporting medium, the television. The analysis of verbal interactions indicates that this genre reflects socio-historical aspects, values and stereotypes of a particular period of time through ideological voices, which are intertwined in discourse. This research confirms that language is a social, historical and ideological phenomenon and that context is very important for the understanding of what is said or of what one wants to say in a television advertisement, which is itself a social utterance (Bakhtin, 1981, 124).
