The growing nonprofit news sector is showing some signs of economic health, and most leaders of those outlets express optimism about the future, according to a new study by the Pew Research Center. But many of these organizations also face substantial challenges to their long-term financial well-being. The report finds that large, often one-time seed grants from foundations help many of these nonprofit news outlets get up and running. But as those grants expire, many organizations do not have the resources or expertise necessary for the business tasks needed to broaden the funding base. More than half ofthe nonprofit news organizations surveyed by the Pew Research Centerin late 2012 (54%) identified business, marketing and fundraising as the area of greatest staffing need, compared with 39% who said the top need was for more editorial employees. In addition, nearly two-thirds of the nonprofits (62%) cited "finding the time to focus on the business side of the operation" as a major challenge -- compared with 55% who cited "increasing competition for grant money."
