Formats for listening to music summarize the information by selecting and reporting the main features and make comparisons where relevant

The two pie charts depict the types of audio formats used in the year 2000 and the year 2010. According to the legend, there are five audio formats including radio, tape, CD, MP3 player, and internet. It is obvious that some formats were used by more people in 2010 including the MP3 players and the internet, while the other formats were either stable or dropping.

Looking at the information in more detail, Internet, which was not present in 2000, and MP3 players were devices that are used by more people in 2010, which were only 0% and roughly 20% in 2000 to 25% and 40% in 2010, respectively. Thus, in the year 2010, Internet together with the MP3 made up nearly 70% of the total formats.

By contrast, the number of people listening to music by cassette players was reduced significantly, with the percentages decreasing from roughly 30% in 2000 became 5% in 2010. Likewise, the radio, that made up nearly 40% in 2000, dropped to only 30% in 2010. Interestingly, these two formats represented the largest portion in 2000. On the other hand, there were no changes to the CD proportion which remained at 30% in 2000 and in 2010.
