The bar chart illustrates the proportion of the sales of five distinct magazines in three separate years: 2001, 2005, and 2009.
Overall, the sales of social magazines considerably decreased throughout the timeframe, whereas the reverse was true for movie magazines. Despite remaining unchanged until 2005, the figure for economics magazines led the chart in the end. Notably, the percentage of music magazine sales rebounded to its initial position after a drop in 2005.
A substantial proportion of sales was recorded in social magazines at the outset, followed by economics magazines, albeit to varying degrees, standing at 40% and 25%. The former then witnessed a noticeable decline to a mere 5% in 2009. The latter, meanwhile, remained at a plateau until 2005, after which it increased to roughly 35% in 2009.
In stark contrast, the percentage for music magazines stood at 10% in 2001, before dropping to 5% in 2005 and returning to its initial position in 2009. The sales of movie magazines were significantly low across all categories in 2001, constituting 5%; however, it surged over the period, reaching 30% in 2009, while the proportion for sports magazines rose from just 16% in 2001 to approximately 19% in 2009.
