Change in the sale of CD's over the last years

Over the last nine years, the sales of CD's has fallen over 52%. This is because the digital downloads have increased so much, for example Itunes. Itunes has become one of the most used programmes to download music online.

Quote found on the internet:
'Driving the point home, approximately 31% of all 12-24 year olds said they had downloaded digital music files from the internet in 2000. 10 years later, that figure has more than doubled to about 65%.'

Youtube has also been another very common soruce of downloading music in the past years, I would say about 5 years now. There are various website which download songs with just the link of a song on Youtube.
