SnagFilms is a free streaming video service that focuses on documentary movies. It appears to be entirely underwritten by Goldman Sachs. You’ll see Goldman Sachs pre-roll commercials when viewing a video. Goldman Sachs does not say why they are underwriting this effort either on the SnagFilms or their own corporate website.
You can tell other people about documentaries you’ve watched on SnagFilms via email, Facebook, or Twitter. I tested sharing information to Facebook. You can see what the resulting status update looks like below.
