With sport at the heart of the pay-TV ecosystem, dedicated online-only streaming services could emerge as a threat to leading players like Sky 

The liveliest newcomer, DAZN, launched in 2016 with mostly second-tier sports. Now in seven markets and counting, it has recently made bold moves into top-flight competitions, notably in Italy, albeit as a secondary player 

History has not been kind to those challenging pay-TV incumbents by selling sports unbundled—particularly in Europe, as Setanta, ESPN, beIN SPORTS and Mediaset can testify. If DAZN can stick to secondary positions in premium rights, or simply less-expensive sports, perhaps it will fare better 

Recorded music revenues in Japan are stuck in decline as physical sales sag, although 2017 marks the first year when streaming gained a foothold with 8 million subscribers. 

J-pop fans spend on 'experiences' with their idols including events, merchandise, CDs and DVDs, which streaming cannot replicate. Top native LINE MUSIC offers integration with a popular messaging app and bundling with mobile. 

Serving international repertoire, Apple Music claims more subscribers than Spotify in Japan, which is more localised, and has most users on the free tier. Amazon Prime Music is a looming constraint on the adoption of subscriptions.
