Somewhere in the dark cavernous hall of Houston Hall in New York City there lies the Great Big Story of the NewFronts.  Last week, Turner invited advertisers to explore their newest initiative: A digital nonfiction-based programming network geared towards a young, socially engaged digital audience.  "Great Big Story is a content initiative that is underwritten by CNN but serves as a standalone company," stated Michael Strober, Executive Vice President Client Strategy and Ad Innovation Turner Ad Sales. "It is a distinct brand to provide another way to connect to audiences," he added.
