In recent years, online video sharing services have been growing rapidly. Nowadays, online video sharing becomes one of the most popular ways to produce and consume media. Moreover, with growing 3-D technologies, the interest to 3-D technologies has increased and it becomes easier to produce, share, and consume 3-D media on Internet. This paper investigates 3-D media production and consumption patterns in comparison to 2-D media to get insight to the online 3-D media ecosystem by analyzing metadata and statistics of 10,597,268 2-D videos and 50,972 3-D videos in YouTube. It is shown that the general production and consumption patterns of 2-D and 3-D videos are similar, but they have differences in uploading patterns, video length, category, and user participations. From these differences, we identify distinguished features of online 3-D video sharing. Our findings will serve as valuable information in technical and commercial aspects of contents sharing services.
