David Ogilvy would become the greatest ad man in history after the end of World War 2 – but in 1940, as England goes into an unequal struggle with Nazi Germany he has to succeed at his toughest, most important assignment ever – he has to convince Americans to help arm England so that it can defend itself, and an even bigger challenge for him, if he can, he has to get America to join the war against Nazi Germany. As a spy for England working in America these would be the most important things he ever did which hardly anyone would know about. But before the war started David Ogilvy was going to Hollywood with Dr Gallup to help the movie studios better serve their audiences.Tag words: Dr Gallup; RKO Radio Pictures; Walt Disney; Snow White; Cary Grant; Katherine Hepburn; Bringing Up Baby; Anne of Green Gables; David Ogilvy; Hollywood; The Little Minister; Sylvia Scarlett; William Randolph Hearst; Citizen Kane; Orson Wells; Joseph Kennedy; Prohibition; President Roosevelt; Public Opinion Research Project; British Security Co-ordination; William Stephenson; His Majesty’s Secret Service; The Confessions of an Advertising Man; Rolls Royce Silver Cloud II; Apple; The Merriam-Webster Dictionar; snail mail; Jennet Conan; The Irregulars; Roald Dahl; Charlie and the Chocolate Factory; James and the Giant Peach; Gerard B Lambert;
