I publish Head Zup!, a video comic strip targeting the store-and-forward entertainment sector.

Store and forward entertainment refers to copyrighted content that is intentionally crafted to be shared. That is to say, content that is designed to be stored on a cell phone and forwarded to other people as picture messages (MMS). Head Zup's goal is to harness the intrinsic viral power of wireless peer-to-peer file sharing by creating parody clips that cellular subscribers enjoy and want to share with others. Head Zup's bite size comic episodes are limited to 10-12 seconds to facilitate frictionless sharing across cellular networks.

Does anyone know other companies targeting this space?
