About CBA

Auf Deutsch lesen

The Cultural Broadcasting Archive is a civil society media and communication platform. We operate an independent technical infrastructure beyond commercial interests. In this way, we promote freedom of expression, media diversity and digital communication. This is our contribution for democratizing the digital media landscape.


Podcast provider

CBA is Austria’s largest podcast provider with completely free access. There are over 140,000 audio contributions in around 50 languages, covering a wide range of topics that are available to listen to and download: ethnic minority podcasts, podcasts about politics, media, music, literature, science, culture or philosophy. The platform helps special interest programs reach a wider audience and enables communication between producers and users.


Contemporary document

CBA is an archive of the social, political and cultural events within the individual regions of Austria and Germany. It has developed into an important contemporary document with a strong local reference since it was founded in 2000. In addition to private use, the archive is particularly open for educational work and research purposes. The platform is therefore recommended as a research source in textbooks, for example (e.g. „Durchblick 3“ for geography and economics, Westermann Vienna).


Exchange platform

The CBA is an exchange platform for contributions from community radios in Europe. We enable the mutual rebroadcast of radio programs outside the stations‘ local reach. More than 40,000 broadcast rebroadcasts from stations all over Europe have been documented since 2004 alone.


Our principles & goals

We are non-profit, non-advertising, both politically as well as technically independent.

Our goals are to promote political participation, media diversity and open access to information and knowledge.

We do not sell personal data. It is important to us that producers remain the owners of their content and, at the same time, we want to ensure that it is as freely available and reuseable by the general public. Therefore, we rely on the use of free licenses such as Creative Commons.

We advocate algorithms that primarily follow ethical guidelines. We want opinion-forming to be possible under democratic conditions, without the public discourse being distorted by opaque algorithms and interests.

We only use open source software and are therefore technically independent of commercial providers.

For our work we received an honorary mention at the Prix Ars Electronica 2010 in the category „Digital Communities“ and a nomination for the „Austrian Prize for Free Knowledge 2020“ by Wikimedia Austria.

  • We provide a non-profit digital infrastructure that stands for open access, privacy and data sovereignty
  • We bring together a variety of engaged, civil society communities to share content on the platform
  • We secure all content in-house and out-house on a daily basis, ensuring long-term availability
  • We provide a range of interfaces and tools through which content can be widely distributed:


Via RSS feeds, podcast directories can list CBA content. Individuals can use podcasting apps and RSS aggregators to subscribe to podcasts and automatically stay up to date.

Websites & Mobile Apps
External websites and mobile applications automatically integrate content from the CBA via our interfaces. We provide customized APIs for this purpose.

For listening, the CBA Player can be integrated responsively into external websites either as a stand-alone on demand service or via embed code.

Sharing & Social Media
CBA content is easy to share on social media.


We regularly contribute to the public debate around the topics of freedom of expression, free access to information, digital self-defense, copyright and digital archives. To this end, we organize discussion events, initiate innovative technical projects, collaborate on publications, or develop positions on draft laws and write statements on them.
