HBO and IFP have joined forces to create a new grant specifically designed for multi-format nonfiction storytellers. The IFP/HBO New True Stories Funding Initiative supports several different types of makers in the early stages of development. It doesn't matter if you're working in print, audio, or, of course, video, as long as your intention lies in bringing your work to life visually. That means that if you want to make short form, feature-length or serialized content, this could be a good one to check out.
IFP explains the grant is for "projects on the arts, humanities, contemporary societal and political issues, and personal documentaries with approaches that range from traditional and character-driven narratives or journalistic perspectives to those more adventurous, creatively risky and formally challenging."
