Melinda Gates told me in an interview earlier this year that she initially eschewed a focus on women's issues, seeing it as one of the "soft" areas typically reserved for female philanthropists.

Driving the news: Gates said she realized that women's issues were actually the key to the other areas that she is passionate about: global health, education and economic equality.

There hasn't been much innovation in women's birth control since the pill came to market nearly 60 years ago — because drug companies don't stand to make much from it, Bloomberg reports.

Where it stands: Only 2% of drug companies' annual revenue from contraceptives goes back into research and development, according to the Gates Foundation.
