People began spreading the word on social media and blogs, as we introduced not only a novel way to advertise on Facebook, but also a novel way to raise funds with your Facebook 'share'.More importantly, within less than a week of launch, brands have pledged more than $10,000 to 'buy' Facebook shares on Share for Smiles, allowing Operation Smile to join the 2.4% of brands who've raised more than $10,000 on Facebook in a matter of days. And because the platform is socially powered, this means Operation Smile did it at zero media cost per dollar raised.
