A series of major advertising deals have been signed this week, starting with the creation of a national online real estate ad network between 282 US newspapers and Zillow.com.

The agreement, Editor&Publisher reports, will see the papers and Zillow sharing each other’s advertising inventories and splitting revenue.

Politico.com has opted for a selective approach in creating an ‘advertising and content distribution network’, says an article in MediaWeek.

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.

Meanwhile in the UK, Birmingham radio station BRMB has joined up with classified advertising site AdFlyer to create a website for motoring ads targeted at the west Midlands. Users can upload an ad for the first week free of charge, a release from AdFlyer said.
