Top domestic video sites spend an average of over RMB 17 million on bandwidth each month, reports Guangzhou Daily quoting Beijing-based user-generated video site Youku.com CEO Victor Koo. Koo said online video site development depends on capital injection from venture capital firms because of the high costs associated with the business including content licensing, server group capacity, bandwidth, and human resources. Youku.com confirmed a $30 million investment led by Maverick Capital and joined by existing investors Brookside Capital, Sutter Hill Ventures, Farallon Capital and Chengwei Ventures on Monday.
