This week, we're taking a look at “Crowd Source," written by Davy Rothbart for The California Sunday Magazine, and published in March 2016. The story looks at a company that provides crowds to clients. For a fee, it can deliver a mob of cheering fans or a noisy crowd of angry protesters.

Davy Rothbart is a bestselling author, Emmy Award-winning filmmaker, contributor to This American Life, and the editor/publisher of Found Magazine.
