The graph depicts the total music sales between 2011 and 2018

The line graph illustrates the amount of music that was sold over a six-year period between mid-year in 2011 and mid-year in 2018. The total percentage of sales is divided into three categories that include streaming, downloading, and purchasing CDs The three different melody formats were first rolled out by mid-year in 2011. According to the data, CDs were the most popular music method at the beginning of the period. Around 55% of the purchases accounted for physical disks. However, over that same year, their figures dramatically dropped and reached around 20% at the end of the period. Conversely, only 35% of people downloaded songs in 2011. This virtual format peaked between 2014 and 2015 with almost 45% of popularity before this trend reversed and steadily fell up to 30%. Furthermore, a rare minority of clients bought streams in 2011 before the method became more popular. By the year 2018, the number of people who preferred this streaming multiplied by five. Overall, what stands out from the chart is that while the selling of streams constantly grew, sales figures of CDs witnessed an opposite trend. Meanwhile, the popularity of downloaded music fluctuated.
