This post has been updated. Knight Foundation uses challenges to find great ideas across its program areas. In addition, a few opportunities are available year round. Here are the opportunities open now: If you have a news or information idea you want to develop and test, the Knight Prototype Fund may be for you. This Media Innovation initiative provides $35,000 to turn ideas into prototypes. There are several cohorts of winners each year; the most recent winners can be seen here. The next application deadline will be in early 2015. Follow #PrototypeFund on Twitter for more. If you have a new idea to make one of the 26 Knight communities more successful, the Knight Cities Challenge is an option. The current round closed Nov. 14. The challenge is a new program from Community and National Initiatives, and winners will share $5 million. The initial application is simple, and reviewers will look for innovative ideas that can help our communities attract and retain talented people, create economic opportunity, or foster a culture of civic engagement. Finalists will be announced in January 2015, and winners in the spring. The second round of the challenge will open later in 2015. #KnightCities
