Still sorting through the News Challenge categories? Knight Foundation’s John Bracken lends insight into them in this video Q and A. If you still have questions, we hope you’ll join us for a live chat about the challenge at 1:30 p.m. Nov. 18. See you then.

Here is the description of the 4 Knight News Challenge categories from the application page >>.

We are looking for projects that address the following:

Mobile: Seeks projects that use mobile devices to produce, deliver, consume, share and otherwise engage with news. The category reflects the fact that the mobile phone, with 5 billion units in use, has become an important tool for news.

Authenticity: Looks for projects that help people better understand the reliability of news and information sources. We’re hoping to identify promising ideas for helping citizens negotiate our oft-chaotic media world. How can we help news users better evaluate the validity and trustworthiness of news and information? How can we better filter and assess the credibility of what we read and watch?

Sustainability: Considers new economic models supporting news and information. New ways of conducting and consuming journalism may require new ways of paying for it. We’re open to ideas for generating revenue as well as ways to reduce costs.

Community: Seeks groundbreaking technologies that support news and information specifically within defined geographic areas. This is designed to jump-start work on technologies and approaches that haven’t arrived yet. Unlike the first three categories, submissions in this area must be tested in a geographically designated community.
