As you might have gleaned from today’s Google Doodle, March 8 marks International Women’s Day. Since 1908, IWD has been used as a platform to build awareness around women’s issues like pay equity, fair labour practices and reproductive rights.

In celebration of IWD, here’s a roundup of links, news, and videos that are sparking conversations about women’s issues.

Perhaps the biggest (read: most controversial) social media story relating to IWD is the “Rock The Lips” campaign, backed by advertising agency AKQA.

With a presence on Twitter, Facebook, Tumblr, and more, the campaign invites women to upload photos of themselves wearing bright red lipstick and share them on whatever social network they use. The goal is to raise awareness by getting over 1,000,000 women to upload photos.

The Washington Post warns that because the campaign doesn’t link to the IWD site, followers of the campaign “may never learn the substance of the women’s issues being raised.”

In the run-up to IWD, AdWeek published The Women’s Issue, composed of a series of articles that provide a consumer-centric breakdown of women in three age groups, “The Indie Woman,” “The Mom Achiever,” and the “Alpha Goddess.”

The issue is chock full of stats and trends (who knew that women aged 55-65 spend more on consumer electronics than their Gen Y counterparts?). Forbes, however, had a thing or two to say about the depiction, suggesting that despite AdWeek’s optimism, the “Millenial Ms.” has “a lot more on her plate than sex, social media and shopping.”

Forbes’ article paints a more even-toned portrait in response to AdWeek’s issue, including stats that tell a less rosy story (“83 percent of college-aged women diet, regardless of their weight”).

A recent post by Fast Company let women do the talking, featuring advice for women looking to climb the corporate ladder by peers who’ve already made it to the top. The advice (“go where the opportunities are”) probably works just as well for men.

You may or may not have seen this hugely popular TED Interactive presentation by Sheryl Sandberg, chief operating officer of Facebook, but in case you haven’t, her message is as relevant as ever: When it comes to leaders in the workplace, we need more women.

Speaking of careers, the hugely successful Little Pink Book, a free digital content provider designed for businesswomen, is getting a boost from top-notch brands. PR Newswire reports that in celebration of International Women’s Day, Coca-Cola and FedEx will be running marketing campaigns on the site.
