In this paper we assess to what extent Oprah Winfrey's speech during the Golden Globes 2018, situated in the new context of the #MeToo movement and the Time's Up initiative, destabilizes the modes of recognition of gender violence, offering an example of the operationalization of the concept of 'ethical witnessing' in communication media brought about by celebrities. In order to do so we consider the connections she establishes between the fight for rights and other fights for recognition, redistribution and participation; the degree of transgression of the reified models of identification of the subjectvictim and the focus on the capacity of agency; and the type of relationship that develops between the subject who gives testimony and the witness. The paper concludes that Oprah's intersectional approach to gender violence, her focus on agency and resistance (verging on heroism), her role as both witness of her own victimization and facilitator of others' testimonies, and her activism and inspiration for others to engage socially and politically, comes close to transgressing the boundaries of the current mode of recognition and representation of gender violence. Nevertheless, the widely accepted image of Oprah as an authority assumes a hierarchical relation that contravenes an ethical dimension of witnessing. In addition, in line with a liberal position, Oprah reimagines the 'good victim' as an empowered individual who overcomes vulnerability, and she envisions the eradication of gender inequality as something that comes from the top down.[es] Time's Up, celebridades y la transformación del paradigma de la violencia de género: el caso del discurso de Oprah Winfrey en los Globos de Oro (2018) Resumen. En este trabajo evaluamos hasta qué punto el discurso de Oprah Winfrey durante los Golden Globes 2018, ubicado en el nuevo contexto del movimiento #MeToo y la iniciativa Time's Up, desestabiliza los modos de reconocimiento de la violencia de género, ofreciendo un ejemplo de operacionalización del concepto de 'testimonio ético' aplicado a la acción de celebridades en los medios de comunicación. Para hacerlo, consideramos las conexiones que se establecen entre la lucha por los derechos de las mujeres y otras luchas por el reconocimiento, la redistribución y la participación; el 1 This article is part of the project La re-significación de la mujer-víctima en la cultura popular: Implicaciones para la innovación representacional en la construcción de la vulnerabilidad y la resistencia [The re-signification of woman as victim in popular culture: implications towards representational innovation in the construction of vulnerability and resistance] (FEM2015-65834-C2-2-P, MINECO-FEDER), funded by Spain's Ministery of Economy and Competitivity.
