Something interesting is happening: the Brattle’s traditional demographic of bookish older men (No offense! We love you!) is being edged out by younger, more diverse, and dare we say, hipper customers. Why? Our photogenic outdoor sale lot has become popular on Instagram, creating a cycle of visits, alfresco shopping selfies, likes, organic advertising, and more visits. We’ll talk about the ways that this social media-driven shift is changing the shop, and the irony of an ultramodern communication network luring people back into the arms of dusty old books, on this potentially viral #brattlecast.
