Media in the Public Interest is the affiliate non-profit organization of Public News Service (PNS), an AP-style news service providing multi-platform news stories to 8,000 news outlets across the country, reaching an estimated weekly audience of 30 million in 37 states.

MPI was developed by the founders of PNS who realized that nonprofits and grassroots organizations needed help interacting effectively with journalists. As a partner organization, MPI would keep the strategic communications work separate from the editorial work of PNS. Thus, in 2003, Media in the Public Interest was founded.

MPI offers programs and services that help thousands of advocates nationwide communicate with greater impact and connects journalists to often marginalized spokespeople to broaden public understanding on the critical issues of our day. By partnering with PNS, MPI has helped launch independent public interest news co-ops in five states.
