This graph offered a refined view of the uneven distribution between ad-focused photos (photos that took advertisements as their intentional targets) (in red) and other photos (on which advertisements were either omitted or only accidentally captured), taking the time period into account. This graph reveals an increased advertising awareness at the end of the period - or more exactly, that professional photographers who chose advertisements as their intentional target were concentrated in the 1940s. This graph has been drawn after the related table (See the "Tables" section - Table 171).
