Transnational feminism
In the "Oxford Handbook of Transnational Feminist Movements", Valentine Moghadam says that "women have worked together across borders since at least the mid-1800s. (55)" What is now called first wave feminism started in the early twentieth century in the West with a focus on women's suffrage. 
During World War II, the United States government gave women jobs because the war had caused a national shortage of labor. After the war ended, Irene Tinker says (oxford transnational), these jobs were taken away but women were no longer satisfied going back to their previous gender roles. Starting in the 1960s in the United States, second wave feminism emerged, defined by women's organization around "equal right to education, employment, and equal pay for equal work, and on sexual and reproductive rights."
Feministing
Vanessa Valenti and Jessica Valenti began Feministing in 2004 while working at the National Organization for Women's legal defense fund (now Legal Momentum), where Jessica felt that young feminists were being excluded from feminist discourse. She describes Feministing's purpose as "a way to get through the mommy filter" and make feminism more accessible to young women through giving an Internet presence for young feminists. Feministing covers topics ranging from outrage on measures to restrict reproductive rights or pay equity to irreverent or bemused coverage of pop culture and art, such as urinals shaped to look like vaginas. The writing on Feministing is not exclusively political, but also concerns feminist perspectives and observations from the staff's daily lives. Sex and sexuality are another frequent topic of discussion; it is sometimes cited as an Internet extension of the third-wave feminist movement. It is wildly popular among young feminists. Feministing also has a comments section. Readers post (sometimes heated) comments on posts by the editorial board and post their own writing at their community portal.
