The line chart illustrates the average Japanese remuneration and the costs of two different types of television (TV) including black&white and color between 1970 and 2000.
Overall,what is the most striking is that while the average monthly salary rose dramatically, the prices of two given kinds of TVs experienced a steep decrease during this period. Besides, it is important to note that although initially the monthly incomes of citizens in Japan was much lower than the charges of TVs, in the end, the former exceeded/surpassed/ overtook the latter by a great deal. This proved the development of economy and technology in this country.
Looking first at the prices of televisions, in 1970, a black and white was significantly expensive, being sold at 110 Yen. However, in the next 10 years, its cost plummeted to merely 40 Yen due to the introduction of the color TVs on the market. During the rest of the given time frame, this figure continued to drop despite the much lower degree, reaching 20 Yen in 2000, just a sixth of the initial price. A similar trend was observed in the prices of color TVs as it also collapsed from 100 Yen in 1980 to 50 Yen in 2000.
As regards remunerations, in 1970, a typical japanese citizen earned a modest 20 Yen per month, which was only one sixth of the price of black and white televisions. After that, this figure climbed gradually, reaching parity with the price of black and white TVs ( roughly 30 Yen ) in 1990 before being equal to that of color TVs ( 50 Yen ) in 1999. At the end of the surveyed period, the monthly income of Japanese was one and a half times the price of color TVs and three times that of black and white ones.
