This study set out to examine ways English TV commercials can influence on language acquisition of learners in English as Foreign Language (EFL) contexts, especially their vocabulary acquisition through survey, interview, and pre- and post-tests on target vocabulary items. The results showed that there was some positive impact of using advertisement on the learners’ vocabulary acquisition: they revealed that they not only gained the knowledge of the target vocabulary items, but also increased the awareness of cultural differences between their native language (L1) and English language (L2). This study also indicates that employing advertisements were able to have very positive impacton the learners’ motivation for language study and the introduction of different cultural aspects. For the implications of using English TV commercials, it was suggested that students needed to get involved in their own learning by having an experience creating their own TV commercials.
