In the 1950’s, radio host Jean Shepherd constructed one of the most infamous literary hoaxes of all time. Annoyed with how bestseller lists worked at the time, Shepherd urged his listeners to visit their local bookstores and request a book that didn't exist. Shepherd supplied the listeners with a fake title, a plot summary and a fictitious author. Soon, the nonexistent book, "I, Libertine
," became a real bestseller.
WFMU has posted a 1968 radio show of Shepherd telling the whole story. Link
