The graph shows Japanese average monthly salary Yen from 1953 to 1983 and the prices of black and white television and color television during the same period

The line graph shows data on the changes in the monthly income of Japanese people and the prices of two types of television during the thirty-year period from 1953 to 1983.

In general, the amount of money they earned increased considerably, whereas the price of television followed the opposite trend. In addition, color televisions cost much more than black and white ones.

In 1953, the income of the Japanese was just below 20 thousand yen per month. Meanwhile, the price for black and white television was 110 thousand yen, which was approximately five times as high as the average salary. However, after a decade, there was a steady growth of around 5 thousand yen in how much money they earned, while the amount they paid for television saw a plunge to 40 thousand yen. Also in this year, color television started to be sold in Japan at 100 thousand yen.

The prices of the two types of television became much more affordable during the rest of the period. The cost of color television plummeted to nearly 55 thousand yen, compared to about 25 thousand yen of black and white models. The figures continued to drop gradually to just under 50 thousand yen and 20 thousand yen respectively in 1983. The monthly salary, on the other hand, witnessed a substantial rise to 30 thousand yen and overtook the cost of black and white TVs in 1973. After that, it soared to around 65 thousand yen in 1983.
