One of the most successful periodicals in magazine history was True Detective Mysteries. An offshoot of publisher Bernarr Macfadden's True Story magazine, True Detective specialized in semifictionalizing real-life crime cases taken from police blotters and making them riveting reading, illustrated by posed photographs, newspaper morgue pics, and police mug shots. The concept was a natural. Circulation soared into the millions. Before long, imitators followed in droves, leading to a new breed of entertainment that survives to this day under the catchall phrase of true crime magazines.
