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 

Online advertising became the majority of all UK ad spend last year, in step with China but ahead of all other major markets. 

Direct response has further increased its share to 54% of UK ad spend, fuelled by the self-serve platforms of Google, Facebook and Amazon, while content media nets just 11% of the online advertising pot.

We estimate that all online-delivered channels - including "pure play" online properties, broadcaster VOD, digital out-of-home and online radio - could account for well over 60% of UK ad spend by 2020, but only with improved commitment to industry governance.
