The years 1907-1913 mark a crucial transitional moment in American cinema. As moving picture shows changed from mere novelty to an increasingly popular entertainment, fledgling studios responded with longer running times and more complex storytelling. A growing trade press and changing production procedures also influenced filmmaking. In ""Early American Cinema in Transition"", Charlie Keil looks at a broad cross-section of fiction films to examine the formal changes in cinema of this period and the ways that filmmakers developed narrative techniques to suit the 15-minute, one-reel format. Keil outlines the kinds of narratives that proved most suitable for a single reel's duration, the particular demands that time and space exerted on this early form of film narration, and the ways filmmakers employed the unique features of a primarily visual medium to craft stories that would appeal to an audience numbering in the millions. He underscores his analysis with a detailed look at six films: ""The Boy Detective""; ""The Forgotten Watch""; ""Rose O' Salem-Town""; ""Cupid's Monkey Wrench""; ""Belle Boyd, a Confederate Spy""; and ""Suspense"".
