The line graph delineates how much money the Japanese earned per month and the cost of two types of televisions from 1953 to 1973. The units are measured in yen. Overall, it is clear that the amount of money of Japanese people increased sharply over all the time of the period. Additionally, the prices of two kinds of TV witnessed a moderate fall between 1953 and 1973, and the number of prices of colored TV was the most notable.
Initially, look first at the incomes of Japanese individuals. By 1953, having been a gradual growth of 10 yen, the salary of citizens experienced a sharp rise to 100 yen, more than twice as high as that in 1958. Hence, a soar recorded to 180 yen of Japanese salary per month hit its peak in 1973.
In contrast, having appeared in 1953, black and white TV prices started at 100 yen and fell gradually by 20 yen in 1958. Subsequently, this type of TV witnessed a plummet to only 40 yen over the period of 10 years, followed by a modest drop to their trough at 38 yen. Likewise, colored TVs were manufactured in 1956, which had the highest prices at 180 yen. Nevertheless, there was a dramatic increase of 70 yen in colored TV costs in 1963, but twice as much as other TV prices. In the last 10 years, the figure for colored TV cost a slump to 90 yen in 1973.
