Rough English translation
This bar charts charts aim to measure the relative importance of various advertising areas in our five usual samples of the newspaper Shenbao: Jan 7, 1914 ; Jan 3, 1924 ; Jan 5, 1934 ; Feb 1, 1941 ; Jan 1, 1949. Borrowing the vocabulary from urban/political geography, four types of advertising areas has been identified, from the smallest to the largest, each one associated to a distinct color and number :
- subdistrict (yellow) : < 1/4 page (1)
- district (orange) : between 1/4 and 1/2 page (2)
- settlement (red) : > 1/2 page (3)
- empire (brown) : whole page (4)
By juxtaposing the five bar charts, one can trace the changes in the sizes of advertising areas between 1914 and 1949.
