The graph above illustrates the distribution of newspapers marketed by a specific company through three various years: 1975, 1995, 2015.
It is immediately apparent that, magazines about sports rose constantly, while there was a continual decrease in fashion. Additionally, food, health and others have fluctuated.
The sales of sport magazines increased from 32% in 1975 to 36% in 1995, and this was followed by another rise to 42% in 2015. However, the fashion had a negative trend, experiencing a gradual drop from 22% in 1975 to 16% in 1995, after which it further plunged to 5% in 2015.
Starting at 10% in 1975, the articles about food increased dramatically, peaking 22% in 1995, but fell into its previous proportion 10% in 2015. 1975 to 1995 saw a drop in the percentage of health magazines from 26% to 20% and evened out at that level in 2015 too. Despite significant increase in the contribution of other topics from 26% in 1975 to 32% in 1995, it plunged to 26% again in 2015.
