Nostalgia

We live in a world where the nostalgia for the past now permeates our present.With online trends like 'Throw Back Thursdays', apps like Timehop and platforms which gives you the tools to make your digital image look like it was taken with an analogue camera, the internet has never seemed so backwards-facing.In this week's episode of The Digital Human, Aleks Krotoski visits imagined worlds and eras long past to explore whether the web is a nostalgia machine.We speak with Professor of Svetlana Boym to trace the origins of the word back to homesick Swiss mercenaries in the 17th century, visit a water park in New Jersey which was reborn through the collective power of online nostalgia and take tea with a vintage enthusiast, who divides his time between working as an air host in a high-flying company, with living in the 1940s.Producer: Caitlin Smith.
