The document discusses the development and use of conventions in documentaries and advertising. It describes using a young presenter, expert opinions, statistics and reenactments in "Food Inc." and focusing on one topic at a time in "Big Fat Gypsy Wedding." For their own documentary, the group used a sociology expert and animated figures to represent survey responses. Their advert features a girl holding Special K to link to questions about promoting an ideal image, and their double page spread shows eating money to link to themes of capitalism. They selected accessible newspapers and branded everything with the Channel 4 logo for consistency.
