We didn't have a feasible business model, let's put it this way, because when we started, the business model is to provide the backend search technology to the portal companies in China. We did that, we came up with very good Chinese search engine technology and we signed up a lot of the Chinese portals in a very short period of time that includes SINA, Sohu, Netease, Yahoo! China and any partol company you can think of in China.
