Mizuko Ito is a Japanese cultural anthropologist whose work on digital media and young people has established her as one of the most exciting scholars in the field. Currently Professor in Residence and MacArthur Foundation chair in Digital Media and Learning, University of California, Irvine, in her early work she focused on the cultural dynamics of children’s computer games and software. She moved on to examine the role of the changing digital media landscape in shaping the identities and social relationships of young people in Japan and the USA, particularly in relation to mobile phones and online anime fandom. Using innovative ethnographic research methods, her writings have been central to understanding the cultural and social consequences of the digital media revolution for young people. She co-authored the Polity book Participatory Culture in a Networked Era (with danah boyd and Henry Jenkins).
