The bar chart illustrates the proportions of sales for five different magazines at a UK company from 2001 to 2009.
In general, while the figures for economics and movies showed a considerable increase, sports magazines experienced the opposite trend. In addition, although magazines that centred around social topics had the highest sales at the beginning of the period, they were eventually replaced by those reporting on economics. The sales for music remained relatively stable, with minimal changes occurring.
In 2001, magazines covering social topics were best-sellers, accounting for 40% of the total sales of the company. This was followed by economics and sports, which were 25% and approximately 18%, respectively. Far below were magazines for music and movies, which in turn constituted only 10% and 5% of the total sales.
Subsequently, the percentage of social magazines sold plummeted to 20% in 2005, and continued to decrease further to only 5% by 2009, making it the smallest figure at the time. In contrast, the sales for economics and movies experienced significant growth. In particular, economics remained unchanged between 2001 and 2005, before a sudden rise to 35% in 2009. The figure for movies showed a less subtle pattern, as it surged to 30% by 2005 and then slightly rose to 35% over the next 4-year period. Meanwhile, the sales for sports magazines fluctuated, reaching a peak of 25% in 2005 before declining to 20% in 2009. Regarding music magazines, despite a moderate drop to 5% in 2005, their figure quickly recovered to 10% in 2009.
