Entertainment entrepreneur Nils T. Granlund (1882-1957) created the first movie preview, filmed the first commercial, was the first to broadcast a live sports event, and, as a popular radio personality, introduced the Jazz Age to America via his broadcasts from Harlem's Cotton Club. He is also acknowledged as the creator of the modern nightclub, introducing the high-kicking chorus line to the stages of Las Vegas. But though he was among the highest-grossing entertainers of the World War II era--and famous enough to star as ""himself"" in several Hollywood films--he died virtually penniless, and today is all but forgotten. This work is a comprehensive biography of Nils T. Granlund, from his herding reindeer in Sweden to shepherding the most beautiful chorus girls on Broadway.
