This book chapter (published in Spanish) looks into the trajectory of the relationship between Internet connectivity in Argentina since its advent 1994, and the ways in which women adopted it and adapted to its subsequent transformations in their struggles for gender justice. From modem connectivity, email correspondence and listservs to smartphones and hashtag activism, this relationship has brought opportunities, but also been marked by unequal connectivity and increasing challenges. Forty years after Argentina return to democracy, public policies are required in order to guarantee women’s right to an online communication available for all and free of violence.
