The result shows that the purposes of using Code-Switching and Code-Mixing as a communication strategy in their promotion and it also shows that code mixing is more dominant than code switching. The advertisers mix-match the languages that they use with English and Bahasa Indonesia because they assume that these practices are the right ones and matching Indonesian words into English makes it sound cooler instead of using Bahasa Indonesia. This indicates that English signifies a high culture and class status while Indonesian is inferior in status.
