The line graph compares how music sales in the US changed between 2011 and 2018, measured in billions of US dollars.
Overall, what stands out on the graph is the remarkable growth in streaming music sales, which surpassed all other sales of music. Notably, sales from downloads and CDs dropped noticeably, while vinyl music sales were the least popular type of music for purchasing in each given year, despite experiencing an upward trend.
With regards to the upward trends in 2011, just under a billion dollars worth of music was sold via online streams, which had more than doubled by 2015. While this type of sales commenced with one of the lowest purchasing ranks, at about $1 million, it then surpassed any categories with a drastic increase for the rest of the given period, marking it as the leading category. However, vinyl music sales were lowest in all years in question regardless of a half-a-billion-dollar rise until 2015, before remaining nearly unchanged by 2018.
In contrast, starting off at approximately $3 billion in the sales of downloads and CDs, with a dominance of the former. While there was the most striking change, the gap between them stood at almost the same as the initial, decreasing moderately to 1 billion and just under 1 billion dollars in 2018, respectively.
