It is noticeable that much of the debate around the European data-driven display space up until now has lacked real input from digital marketers and CMOs - the real decision makers in the media buying process. Where are the marketers in these discussions around the future of media buying? As an industry we like to make assumptions about what's best for the client (in this case the advertiser). I believe Stuart Colman, Managing Director, Europe at AudienceScience, described this "second guessing" strategy best when he labelled it the media-tech-alphabettie-spaghetti bubble. All stakeholders are already well represented at the upcoming ATS London event. But in the interests of broadening the discussion beyond the ad tech bubble, ExchangeWire is today announcing that all digital marketers working on the advertiser side will be allowed to attend the full-day conference for FREE! There are already a number of senior global CMOs attending the ATS London event. This initiative will look to bring more marketers into the debate. There will be a limit on the number of free places available so do get in touch. If digital marketers are interested in attending, then send your details to info AT exchangewire.com.
