The Echo Chamber podcast series, now in its third year, returns for 2015 with a new show that features Cohn & Wolfe's Jim Joseph breaking down key marketing lessons from the recent Superbowl. While Joseph notes that Superbowl advertising in isolation is typically ineffective, well-rounded digital strategies are helping marketers use the sporting event to their advantage. He also points to the rise of dads as a key marketing trend to watch in 2015. Meanwhile, CCgroup MD Richard Fogg joins the show to explain why his UK PR firm is attempting to help international marketers understand the US media. And last, but not least, M Booth digital head Amber Roussel talks to me about her experience supporting digital engagement for President Obama's State of the Union speech. The White House, she notes, is keen to broaden social media outreach as it attempts to connect with a younger audience. The Echo Chamber podcast is produced by Markettiers4DC.
