Being a simple chap, I like to divide the bulk of the media agency world up into planners and buyers. I know everyone has far smarter and possibly more accurately descriptive job titles these days, but fundamentally you're either a "hot" buyer (driven by the deal) or a "cool" planner (driven by the data). The holding companies' media agencies are facing the severe challenge of pivoting from a buying-led revenue model based on a historic lack of interest, involvement and knowledge from their clients, to a planning-led model driven by openness, transparency and client-facing business solving. Key to a successful pivot is convincing clients to pay for something (planning) that the majority of network agencies never thought to charge for before. It's tough to explain that this change of heart has come about as a result of a need to replace revenues from rebates. Some are managing this better than others. Those who have invested in technology and the ability to derive insights from data and research are likely to fare rather better than those who see the word "transparency" less as an ethos driving how they operate and more as a term in a contract to be worked around and argued over as much as possible.
