Time Out Chicago's president and editor-in-chief Frank Sennett wrote a cover story on the inner-workings of Groupon. After working on the article, Sennett realized he had much more of a story to tell and went about authoring a biography about the meteoric rise (and potential fall) of the online coupon company. The book is called "Groupon's Biggest Deal Ever" and Frank Sennett joins host Steve Edwards for a conversation about the infamous Chicago company.
