Future of TV Advertising international keynote Jon Evans is Chief Customer Officer at marketing effectiveness data firm System1 – and one of the world’s top marketing podcasters. He's on a mission to help marketers hold the line and sell-in emotional, creative campaign investment to rational, hard-nosed exec teams by better predicting its P&L impacts. While the media industry obsesses on the medium – optimising channel mix, ROI, CPMs, the value equation of the channel – fully half of the business outcome depends on the creative, i.e. the message, per System1’s analysis of 100,000 campaigns. But that message is getting lost says Evans. He wants to help CMOs avoid getting fired by arming them – and the C-suite – with the data to better predict how their ads and massive media investments will perform over the long term. Which just might counteract the accelerating rush to performance channels, with Coke the latest, as marketers seek any kind of validation in the face of exploding remits and intensifying short-term pressure. Plus, he has a toolkit for brand marketers and agencies that unpacks how to build mental availability, cut through and more predictable business results on which to base their media buys.
