Indeed, as Ryan and Colley (1967) observed in their classic study of client-ad agency relationships, there are only two causes for why capable agencies produce mediocre advertising for their clients: "Either (a) the client and age ncy are mismated; or (b) the client and agency have not yet learned how to get their respective resources together."
Thereafter, from Gustave Flaubert's Madame Bovary (1857) through Tolstoi's Anna Karenina (1875/1877) to Theodor Fontane's Effi Briest (1894/1895) the novel showed increasing sympathy for mismated women victimized by the moral premium placed on marriage and motherhood.
