Content communities are sharing media content between users. Content communities exist for many different media contents, like texts, photos and PowerPoint presentations. The users of content communities do not need to create a personal profile, and if they do it’s just simple information like the date the user registered and how many videos are shared. From a corporate perspective, content communities carry the risk that copyright-protected materials can be uploaded on the sites. Even though the big content communities have rules so they can ban and remove this kind of content it is difficult to completely avoid, especially popular TV-series are uploaded to YouTube just hours after being sent on TV. The positive side is the popularity of these channels; it is a very good contact channel for firms. Cisco and Google rely on content communities to share recruiting videos, and addition to that – speeches and press announcement they can share with employees and investors.
