TV commercial messages are part of the answer. Rationale Commercials are authentic. Commercials have not been fabricated, arranged, or simplified for the consumption of the language learner, but have been created for native speakers. Similarly, exposure to commercials in the classroom engenders in students a stronger sense of language autonomy - the feeling that they can actually function linguistically beyond its walls. Finally, in EFL situations, overseas images appeal to students who may not have a chance to travel abroad in the near future, but still want to taste different cultures.
Commercials are short, focused, and thematic in content.
They present entire encapsulated and freestanding messages which can be manipulated and digested in less than one lesson. Students tend to stay on task longer and see a clear start and finish to the activity because of commercials' concise aims and brevity. A commercial can easily be found to introduce, review, or wrap up the themes of any lesson, because each introduces one main concept, ranging from sports, cars, and restaurants to AIDS and environmental concerns such as global warming. This variety in concentration is paramount in content-based teaching which intricately interweaves subject matter and language skills. Commercials contain culturally-loaded slices of modern society.
