To complement our featured content series this week with Boston’s leading experts and innovators contributing articles on the topic of advertising technology, we wanted to include the best related infographic around for your Friday enjoyment.

This particular infographic was put together by MDG, a leading advertising agency with offices in Florida and New York. They looked specifically at the technologies driving what they describe as a “deep transformation” happening in the advertising world. Themes we love in this infographic: brand engagement, the proliferation of online media (specifically, video, mobile and social) – and even some outbound vs. inbound terminology (thank Boston’s HubSpot for coining that term!).
