Time magazine has launched a special multimedia project, Firsts, celebrating women who became the 'first' to break barriers and achieve career milestones.

Stars including Hillary Clinton, Barbara Walters, Oprah Winfrey and Selena Gomez grace the covers of the special issues, and Time magazine's Editor-in-Chief, Nancy Gibbs, commented 'This is not a power list, this is not most famous women or most wealthy women. This really is women who have stories to tell about breaking barriers that we think are instructive and inspiring across so many different fields'.
