The rise of streaming services has definitely changed how we consume music. It's also changing how record labels make money. In its earnings report for Q1 2016, Warner Music Group, one of three major labels alongside Sony and Universal, revealed that streaming is now its biggest source of revenue in terms of recorded music. It also says it's the first "major music company" to report this transition. More specifically, Warner's revenue from streaming rose $72 million during the quarter, putting it ahead of physical sales and digital downloads for the label. Of course, the decline of physical sales has been well-documented both globally and in the US.
