The pie charts show music devices used from 1990 to 2010. Overall, the most used gadget was the compact disc(CD) initially, though digital audio devices became popular in 2010 despite not being used at all in 1990. Vinyl records and cassettes were the other types of media that were used.
The main audio medium in 1990 was the CD, being responsible for over a half of the musical devices used in that year. A decade later, its dominance continued, topping the charts with a massive 95%. However the compact disc relinquished its top spot in 2010 to the new fan favourite, named the digital Audio(60%), which gained popularity from 2000(5%) , but was never used prior to that.
The proportions allocated to the vinyl record and cassette were 20% and 25%, respectively. However, the next 10 years saw both disappear from the scene, though the vinyl record made its way back in 2010(5%)
