Hot on the heels of ISBA and PWC releasing their groundbreaking study on the programmatic supply chain, reported in the FT, Marketing Week and trade press, I talk to the two guys that led the study to dig deeper in to their findings and the implications. 

Steve Chester, Director of Media and Sam Tomlinson, Partner of PWC tell me why it took 15 months to get the necessary access to data, why only 12% of impressions could be matched and unpack the headline stats around 1/3 of costs being unattributed. 

We discuss the value of programmatic, the need for education, implications for marketers, potential solutions and the rally cry for the whole industry to collaborate.
