The recent emergence of an increasingly participatory media culture has opened up new ways for audiences to collectively negotiate the cultural meanings surrounding celebrities. Public screens are one such phenomenon, where people gather to witness the live broadcast of celebrity events. Taking our point of departure in two recent royal weddings in the UK and Sweden, we explore the performative displays that public viewing affords, as participants interact with the event on screen, with other participants, and with media representatives in the venue. This article provides a fresh analytical perspective on how audiences engage with royal celebrities in such mass-participatory consumption contexts, illuminating a little-studied area of celebrity culture.
