With c.22m accounts across 44m devices, Roku has a US footprint which exceeds the largest pay-TV platforms

Limited competitive advantages highlight the scale of this achievement, but also leave the pioneering firm vulnerable to activities from bigger, wealthier rivals Apple, Amazon, and Google as well as pay-TV providers

The odds are stacked against Roku, but continuing the innovation in production and product that built its lead may secure future success

Linear TV is still a mass market medium, watched by 90% of the UK population each week. However, our latest viewing forecasts predict broadcasters will account for two-thirds of all video viewing in 2028, down from c. 80% today, due to the relentless rise of online video services

Total viewing will continue to increase as more short-form content is squeezed into people’s days, particularly on portable devices, but the key battleground for eyeballs will remain the TV screen

The online shift has already had a huge impact among younger age groups, with only 55% of under-35s’ current viewing to broadcasters. Older audiences are slowly starting to follow suit, but have a long way to go

Children’s media use and attitudes have dramatically changed over the last few years, stemming from the rapid take-up of smartphones and tablets

Traditional TV continues to decline at the expense of newer video services such as YouTube, Netflix and Amazon, with 43% of children aged 8-15 preferring YouTube videos over TV programmes

These online services offer content producers wider opportunities, but questions remain around the lack of regulation online, and the recent scandal around children’s safety on YouTube has heightened these concerns

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
