The bar chart illustrates the proportion of various types of magazines sold by a company over a 40-year period, from 1975 to 2015.
Overall, sales of sports magazines showed a consistent and significant increase throughout the period, while the proportion of food and fashion magazines experienced a noticeable decline. Similarly, sales of health magazines and those categorized as “other” also followed a downward trend.
In 1975, food magazines accounted for approximately 10% of total sales, while fashion magazines constituted 23%. By 1995, the share of food magazines had increased sharply to 21%, but it subsequently fell to its original level of 10% by 2015. Meanwhile, the percentage of fashion magazines declined steadily to 15% in 1995 and further dropped to 10% by 2005.
Sales of health magazines began at 26% in 1975, experiencing a sharp decline of 20 percentage points by 1995. From then onwards, this category remained stable at 6%.
In contrast, sports magazines exhibited consistent growth, starting at just 10% in 1975 and rising steadily to reach nearly 43% by 2015. The “other” category showed an initial increase, peaking at 31% in 1995. However, this figure dropped to 25% in 2005 and continued to decline thereafter.
