YouTube is the biggest pool of cultural data since the beginning of recorded communication, with 400 hours of video uploaded every minute. In his new book, Videocracy: How YouTube Is Changing the World . . . with Double Rainbows, Singing Foxes, and Other Trends We Can’t Stop Watching (Bloomsbury, 2018), Boston College alumnus Kevin Allocca lays bare what YouTube videos say about our society and how our actions online are changing the face of entertainment, advertising, politics, and more. An expert on the intersection of web video and global culture, Allocca is YouTube’s Head of Culture and Trends, tracking popular video phenomena and managing trending content initiatives.
