Ad fraud and viewability obstacles in the programmatic trading space are putting mainstream TV broadcasters off serious conversations about the technique’s potential, according to ITV commercial director Simon Daglish. Speaking at MediaTel’s Media Playground conference in London, Daglish spoke of his concerns around third party data, and said it was “hard not to believe” that the problem of ad fraud was similarly as prolific in the UK market as the US, where figures estimate as much as $1bn of ad spend is wasted.
