Dear Mark Allen,
        In research I did on early cinema I found the use of the term
"trailer" occurring in the mid to late teens and having the meaning of a
short film prepared as an advertisement for a forthcoming movie.  See
"Announcing Wares, Winning Patrons, Voicing Ideals:  Thking about the
History and Theory of Film Advertising," Cinema Journal 29, no. 2 (Spring
1990), p. 8 and fn. 24.  Hope this helps.  Janet
