How I started a sanitary napkin revolution!
When he realized his wife had to choose between buying family meals and buying her monthly "supplies," Arunachalam Muruganantham vowed to help her solve the problem of the sanitary pad. His research got very very personal -- and led him to a powerful business model. (Filmed in Bangalore as part of the TED Global Talent Search.)
This talk was presented at an official TED conference. TED's editors chose to feature it for you.
