Broadcast radio has maintained its reach and listening time over the past decade: younger people listen less than before, but this is made up for by an ageing population.

The challenges to radio come from changes in distribution technology in the home and in cars, and from product innovation in the online audio space.

Over the next few years, we predict continued stability in radio, but as technology brings it into closer competition with online audio, broadcasters will have to continue product innovation.

For the second consecutive year, the global recorded music industry body IFPI reported rising trade revenues, growing 5.9% to reach $15.6 billion in 2016

Our forecasts supplement IFPI’s trade revenue data with richer national-level consumer expenditure data from local bodies in core markets, and project CAGR of 2.3% to 2021, tapering off as streaming approaches maturity

This fairly modest topline growth for global recorded music streaming trade revenues is the product of our judgement that the marketplace remains awash with free music. Streaming trade revenue growth could be higher still if the industry finds a solution to piracy through technological or regulatory means, obviating the need for the ad-funded compromise

Streaming is now mainstream and we predict 113% growth in expenditure on subscriptions for 2015-18 in the top four markets (US, UK, Germany and France)

Free vs paid-for streaming is the central question for the music ecosystem: free yields fractions of pennies, making subscription the only credible business model

Market leader Spotify is facing competition from tech giants Amazon, Apple and Google, with deep pockets, for whom content is a pawn in a larger game
