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 

Recently we attended the inaugural IABUK Digital Upfronts, in which 11 digital media companies pitched their wares to advertising agencies and advertisers.

UK growth in internet advertising is now powered by mobile, social and video, and these three areas were the focus of the Upfronts.

The Upfronts are symbolic of the rising importance of digital media in the UK and worldwide; while broadcast television remains the king of brand advertising, marketing and advertising are becoming less TV-centric.
