I know there are companies looking for CRM (customer relationship management) software, and that stuff can be mighty expensive.
While helping someone find something to do the job, for free, I came across this one today:
Cream:
A free, open-source CRM for media organizations
Cream is a multilingual customer relationship management (CRM) system for media organizations that features powerful modules for sales automation, customer service, subscription management, incoming and outgoing email, template-based HTML newsletters, and a WYSIWYG editor.
They also have some other free products:
Dream:
A distribution management system for print publications
Dream is a powerful and user-friendly system for tracking print distribution and circulation. It uses many principles from customer relationship management (CRM) systems, but in a way specific to print publishers.
Campsite:
Open Source Newspaper/Magazine Software for Web Publishing
Campsite is a multilingual web publishing system that can bring your newspaper or magazine content to the online world. It is often used by media organizations who also have a printed version of their publication, and enables them to increase their revenues with online subscriptions and ads. There are many systems that might seem similar to Campsite, but it is the only open source system designed to work in the same style of newspapers and magazines - for example, with multiple journalists, editor review, issue publishing, and subscription management.
Campcaster:
A free and open source automation system for radio stations
Campcaster is an open source radio management application for use by both small and large radio stations (yes, real radio stations, not internet radio) to schedule radio shows. It provides both live studio broadcast capabilities via a desktop application called Campcaster Studio as well as remote automation via the Campcaster Web interface. Campcaster has networking components that make it easy for affiliated stations to share their content with each other, either over the Internet, or by exporting content to removable media for ground transport. This latter method is necessary in many places where there may be little or no Internet connectivity. You can create mashups with other applications using Campcaster's XMLRPC interface, which is supported for the audio storage module and the scheduler. Campcaster runs only on Linux.
Everything they have is free and open source, but if you want support it will cost you. They do accept donations and the company is even a 501(c)(3) public charity, so if you live in the US and donate, it's tax deductible.
