The rise of digital musicIn 1997, the global music industry belonged to the Big Four (including four record labels: Sony-BMG, Warner, EMI and Universal) achieved $45 billion in revenue, an unprecedented figure in history. However, since the launch of the two P2P (peer-to-peer network) sharing software Kazaa and Napster in 1999 and 2004, the label has begun to experience its peak on the downward slope. Since 2000, global music sales have fallen to 25 to 30 billion per year. With this rate of decline, by 2009, global music sales were only 21-23 billion.

In 2007, this figure was 3 billion. The total number of songs downloaded from the Internet has reached 5 million in more than 500 digital music stores worldwide.

Under these circumstances, CD sales were in sharp decline. That's why, in 2007, it was the Big Four's time to survive: they were trying to convert most of the business models from CD to digital music to save them before it was too late.

A business model based on advertising has also been implemented by a certain number of digital music stores like Napster or Rhapsody: Listening to music is free and you will only be charged when you download this content. In 2007, websites that distribute music online (web radio) have. also been recovered after the RIAA copyright lawsuit. This shows that respect music copyright is the best way to ensure long-term profits for all three parties: listeners, music providers. services and music companies have also created separate social networks for fans, as well as listening to music services separately, usually under the name Sony-BMG's MusicBox. discs began to move from an indirect form (through the retail system) to a direct form (direct approach to consumers).).
