The Importance of Being Earnest was NBC’s first coast-to-coast broadcast of a play in 1929. It was ideal for radio, partly because Oscar Wilde’s crisp dialogue obviated any need of facial expressions or gestures. Epigrammatic speech, as Noël Coward found, was a signifier of modernity in the 1920s. Beyond that, as Kate Hext shows, the America of Calvin Coolidge and Herbert Hoover had a sinewy and hardy sympathy for the Anglo-French fin-de-siècle literary mode of the 1890s known as Decadence.
