This paper aims to investigate the potential of printed computer advertisements (between 1970 and 1990) in the development of communicative and written competence in English language along with teaching computer technologies. The research was conducted with 179 printed computer advertisements and the data was taken by the help of Abbyy Finereader and NoteTab software. The different words they contain were counted and grouped under the parts of speech. Findings have been compared to the same word count analysis conducted to French as a foreign language course book. The results show that the advertisements examined are very rich sources by means of linguistics and they can be employed in foreign language teaching classes as support material. At the same time, they can be used in technology classes as they contain chronological data. [This paper was presented at INTE 2015.]
