Along with all the people there are tons of brands here at South By Southwest, and the marketing strategies for the companies behind those brands are evolving. As the conference transitions from tech to music, we met up with Quartz senior editor Zach Seward to discuss this marketing evolution. Plus, we were lucky enough run into the actress Rosario Dawson at the convention center. She's been in movies like Quentin Tarantino's "Death Proof" and the upcoming biopic about civil rights leader Cesar Chavez. But she was in Austin to talk about supporting makers in Africa and social organizing for Latinos on Social Media.
