At present trends, there has been a great rush to jump on the video bandwagon and use this form of media in the ELCS lab for developing communication skills. This paper points out that video, with its combination of visual and oral information, has an intrinsic attractiveness for students of Science and Technology, and advertisements with their 30 second barrage of language and culture are an excellent source of authentic material that are more manageable in length than sitcoms, full-feature movies, or programs. This paper then discusses that one of the most compelling reasons for using video form advertisements is that they are the ideal source of innovative and fun ELCS lab activities in content-based lab classes because they can be tied to a particular theme or chapter in a textbook. Finally, a sample lesson is outlined using pre-viewing activities, viewing the video form of advertisement, language processing, securing adequate comprehension, discussing cultural and values laden components and follow-up activities to tap into the potential of the commercial medium.
