Fashion underpins the growth of ecommerce; online took a 14% share of all fashion retail in the UK last year and is set to rise further, challenging the economics of physical retail 

Mobile is a key driver, it is changing research and shopping habits, and in turn affecting supplier product cycles, merchandising and marketing strategies 

Social media has disrupted the traditional shopping funnel, changing how trends and styles proliferate and shifting the sites of authority and influence in a £66 billion sector

This year marked the second annual IABUK Digital Upfronts. As well as Facebook, Google/YouTube, Aol, Yahoo!, Twitter, BuzzFeed, Vice and others, several traditional media companies – Sky, The Guardian and Global Radio – participated, reflecting the rising importance of digital media and digital media buyers to their businesses

Many of the pitches were informed by the key shifts in online content: it is increasingly cross platform, driven by mobile devices and focused on video programming, and these formed the main themes of the event
