The parodic nature of ‘decade-ism’

From n+1 magazine: "Historical pastiche is one of our most important art forms, cutting across all media. We come to know it best through what we might call 'decade-ism,' the artistic practice of parceling out history in 10-year spans. There is a menu of decades to choose from, and an audience with sophisticated tastes in recent period detail waiting to sample the latest clever, self-aware tweaking of classic ingredients. That TV serial set in the Sixties? It's as rich as it looks, but the bitter aftertaste tells you the chef is sending up the clichés."
