With old economic models collapsing, non-profit investigative journalism websites funded by foundations or wealthy individuals have sprung up around the country in recent years.
They've produced some excellent work - ProPublica, one of the best-known non-profit news sites, won a Pulitzer Prize. And proponents of so-called entrepreneurial journalism have hailed such sites as models for new ways of funding news organizations.
But how do such sites maintain their editorial independence when they're being funded by groups that often have very specific missions, political and otherwise? That's what concerns journalism professor Stephen Ward, who runs the Center for Journalism Ethics at the University of Wisconsin-Madison journalism program.
