The digital music business is expanding globally as streaming and subscription services surge in popularity. Streaming and subscription revenues grew by over 50% in 2013, exceeding $1 billion for the first time. The number of paying subscribers to subscription services rose to 28 million, up from only 8 million in 2010. Downloads still account for about two-thirds of digital revenues but this is declining slightly as streaming grows. Physical formats still generate over half of global revenues. The music industry market varies globally, with some countries favoring downloads and others streaming, leading to a mixed economy of revenue streams.
