With Voz in market and the TV networks seemingly moving forward with a BVOD marketplace, agencies and broadcasters have renewed impetus to converge TV trading and buying and flick legacy systems. But ditching decades of behaviour is never easy. Perhaps the best example is what has been dubbed the Unilever trial, where the FMCG giant, agency PHD and Seven West Media used early Voz data to boost reach by 20 per cent while cutting audience duplication to four per cent by combining linear and BVOD. Alex Tansley, Head of Converged Audience Trading at Seven and PHD investment chief Joanna Barnes were key architects of that trial. They unpack what converged TV trading will look like in the next 12 months – and what that means for marketers, media agencies, TV networks and perhaps ultimately the pure-play streaming platforms now entering the advertising game.
