WNYC had a problem promoting their podcasts. They wanted to share them on social media, but sites like Twitter and Facebook are geared to the visual instead of audio. Their solution was to convert their podcasts into video clips and they created a tool for this Audiogram. It’s proven very successful for them.

More recently Sparemin has developed the concept and developed a website Headliner, which can take audio files and make them into video. With some added features. From my point of view, the most interesting feature is that you can reformat the videos from landscape to square or portrait – and that way you can share in more social media friendly proportions.
