From an article posted by APG Sweden:
The 1880s was the beginning of systematic sales processes. A company that sold calculating machines, The National Cash Register Co., invented a four-step formula for selling – get attention, provoke interest, create desire, and then get action by closing the sale (“AIDA”). The need to make face-to-face selling more efficient resulted in “salesmanship in print”, a term that would make Lord & Thomas the biggest agency in the world. Advertising was seen as a substitute for face-to-face selling, and as a rational, information-based process, with no room for humour or eccentricity. What is noteworthy was that all this happened before the concept of “marketing” was seen as an activity distinct from sales (the first university marketing course was taught in 1902).
AIDA was the first of many “hierarchy of effects” models. Other models are Daniel Starch’s (1920) read, understood, remembered, and acted upon and Russell Colley’s (1961) awareness, comprehension, conviction, desire and action.
