Below is a interview with GroupM's CFO in MediaPost.
The subject at the heart of the interview, is that he drops a bombshell on RTB's they they well move all their business away from that model completely.
What is quite fair to assume, is that their business will utilize companies using Programmatic, such as ADJ.
Seeing GroupM last month signed a contract with ADJ's Symphony for a further 5 years, it's not out of the box to assume ADJ may pick up all that business.
