Qiyi.com, China’s Hulu clone, recently launched in-video links.
When a user hovers mouse over the role in the video, a tooltip box will show up in the video with actor and the role information played. Links are also included to Baidu Baike (a wikipedia like website) where users can find out more about the drama or movie being watched.
No doubt as Qiyi’s user base expands, there will be more advertising opportunities just like in-video links. However, Qiyi must be very careful not to piss off the users when ads over flood.
