The Menace of the Motion Picture by Anna Steese Richardson  (Pictorial Review, October 1910)

Editor's Note - Pictorial Review offers no apologies for publishing this article. Nothing printed in this magazine for years has so thrilled those who have the making of this periodical in hand. We believe it will thrill parents in the same way. When your family physician discovers a cancerous growth eating its way toward the vital organs of your child, he does not decided against the knife simply because he knows the operation will hurt your feelings. This article is the knife laid at the root of a hideous danger which threatens your child, your neighbour's child, society in general.

The real menace of the moving picture habit, which has the youth of America in its grip, is the dark auditorium.  Evil has always lurked in dark corners, and in the darkness of the motion picture theatre to-day, moral degeneracy with red-rimmed eye and loose-hanging lip, lies in wait for youth and innocence. Here the cadet, the white-slave trader and the woman who builds her gains on the weaknesses and foibles of her own, lure their prey on to ruin. Men who accost small children on the street and lure them into dark theatres, have in mind liberties so vile that one could wonder that they could trust the darkness of the theatre to protect them.

See, at the center of the auditorium, an honest mechanic and his children. He has come to be thrilled (hmm: not quite the same sense of the word used above) by a picture drama or moved to laughter by a flickering comedy. But just behind him sits the procuress. For her purposes, the dance hall and the skating rink, all rolled into one, offer no such harvest as the moving picture auditorium.

(This article, like ALL the articles in the era's magazines, is long and goes on to describe incidents in lurid detail.)
