There is a coalition of NJ-based non-profits that has started a petition website named "Keep the NJ in NJN." They are running ads on the NY Times website.
This is how they describe themselves:
"Keep the NJ in NJN is a coalition of organizations committed to saving a public interest voice that has showcased local history and culture, exposed environmental crises, and shined sunlight on the darkest corners of state and local government. While we need to change the way NJN is structured, without continued state support for a truly New Jersey-focused TV station operated by a New Jersey entity, we jeopardize the New Jersey coverage we love, need and demand."
