US newspapers, including The Philadelphia Inquirer, aggregators, and local TV news websites are among 40 outlets signed up to the network.
Under the partnership the media organisations will carry Politico content on the political sections of their websites and feature ads sold by Politico’s sales division. The outlets can also run their own ads alongside Politico content.
Yahoo and POLITICO are to live stream a series of breakfast debates from the US Democratic and Republican National Conventions, which will be held in Denver in August and in St Paul in September respectively.
The panels will be moderated by Politico editors and will be open to convention attendees and the general public.
Local papers The Denver Post and St Paul Pioneer Press will also cover the events.
“It is hard to imagine more exciting partnerships at a more important time in this historic campaign. These events will offer politicians and the public access to unique and powerful audiences: the local community via the host newspapers, political enthusiasts via POLITICO and the world via Yahoo! News,” said John Harris, POLITICO editor-in-chief, in a press release.
