National Geographic Magazine is the top 6th major US magazine of subscribers and has more than 100 years of history. Now, the electronic archive of the magazine is available on 32 CD-ROMS and we can access to all pages including advertising pages. In this research note, I tried to search advertising pages of US auto makers (GM, Ford, and Chrysler) and got more than 300 pages on last 80 years. Then, I transformed the text on each page into data records which can be analyzed based on a text mining tool. Based on a reference dictionary to identify advertising message of each auto maker, the text mining tool does the time trend analysis of advertising copy message and the cross section analysis among 3 auto makers. This is a preliminary analysis and will be extended in the future to the more complete analysis in auto industry and will be extended into other industries.
