You hardly ever see pictures of men carrying women in their arms these days, but once upon a time such pictures made up 71.32% of all illustrations in women's magazines.
Readers of Redbook, Good Housekeeping, Ladies Home Journal, Cosmopolitan and McCall's all seemed to love these pictures.
Apparently, women realized they could travel faster, and usually in a better direction, by walking on their own two feet.
Of course, there could be other explanations for why these illustrations were so popular with women. If you accompany a man to the cave of the winds, being carried gives you deniability about assent. In a subtler era, ambiguity about assent could play a significant role in your relationship with the man, or with your mother. In the second half of the 20th century, ambiguity would become less important.
Or perhaps these illustrations began to lose their charm as women looked at this same theme in men's magazine illustrations, and realized what was going on in the heads of the lummoxes who were carrying them:
If you look at the old illustrations of men carrying women, you see that (politics aside) there was a lot of room for play and psychology as a result of the fact that nature had endowed one sex with the physical strength to lift the other.
But whatever the reason, those nuances are no longer of much interest, so neither are the illustrations.
The end of the demand for such pictures (rather than the invention of television) may be the real reason for the shrinking illustration market.
