Dear Jack ... It's December, and it's my last month at GroupM. I thought I would take the opportunity to write to you and to your readers, mostly to say thank you to everyone that allowed me a close-up view of the great disruptors and the change they continue to catalyze in the businesses they disrupted, including ours.
Rob Norman works with multiple enterprises in media distribution, creation and research, and companies developing new technologies in advertising and marketing.
