Online news sources run by nonprofit groups are becoming major players in many cities and towns, but some question whether they are financially viable, reports The New York Times.

Many of the sites have been backed by foundations and other wealthy donors and have yet to find other sources of revenue, the newspaper notes. But the groups have done well enough that they are now banding together in hopes of attracting national advertising and foundation grants they could not have obtained on their own.

See The Chronicle’s article on the growth of such nonprofit news organizations.
