The Birth of the Sitcom and David Lynch Sings

The Birth of the Sitcom and David Lynch Sings. This week on Culturetopia, our weekly roundup of arts goodness via podcast, you'll hear the insightful author Jeff Yang on Asian-Americans and comic books. And that immortal "Yoo-hoo!" echoing through your headphones emenates from rediscovered radio icon Gertrude Berg, who can fairly claim to have invented the sitcom with her serial "The Goldbergs" starting back in the late 1920s. Plus, we've got a great movie chat with director Mark Webb, who talks about how making music videos influenced is new romantic comedy, "500 Days of Summer." Best of all? You'll hear David Lynch, director of Blue Velvet and Mulolland Drive, sing. And he talks about why the world isn't doomed, not just yet.
