Ernest A. Dench, Advertising by motion pictures (1916)
“ Motion-picture publicity is so pliable that arranging with movie theaters to put on a film of your product in the making and equipping salesmen with a reel and apparatus to demonstrate before prospective customers does not exhaust its uses.I have unearthed a New York manufacturing concern in a large way of business who have fathomed the all-important matter of deriving the fullest value from their movie-advertising investment. They utilize their film to teach salesmanship to the employees. ”
