The line graph illustrates the amounts of wages (Yen) and the values of black-and-white and colored televisions for Japanese people between 1953 and 1973.
Overall, what stands out from the graph is that, while the prices of black-and-white and colored televisions experienced a considerable downward trend during the period, the Japanese average monthly salary increased only slightly throughout the period. Another interesting point is that the monthly wage was the lowest figure initially, and then it was the most raised figure in 1973.
In detail, colored television started at ¥180 in 1958, and it was mostly higher than others. While the prices of colored televisions decreased significantly by about ¥110 in 1963, this figure showed a slight decline of ¥90 by the end of the period. Similarly, the values of black-and-white televisions began at ¥100 initially, before decreasing gradually to just under ¥40 from 1958 to 1973.
By contrast, the Japanese average income was the lowest paid, approximately ¥30 in 1953, and followed by a consistent upward trend to ¥100 in 1968. After undergoing a sharp growth to ¥180 in 1973, it was the highest price.
