linking UGC with the internet as only publication medium limits its range without cause. Indeed, UGC could be understood in a broader sense as multimedia-driven including emerging mobile devices and converging media (for a definition of new media platforms see Appendix IV). It has been stated that mobile services, video platforms (IPTV) and game consoles will give additional impetuses to UGC in future. Nevertheless UGC can be basically allocated to the online delivered content classification by LOEBBECKE which is characterized by the attributes digital, online and unbundled.
