--FILE--Chinese employees serve visitors at the reception desk in the headquarters of Alibaba (China) Technology Co., Ltd. in Hangzhou city, east Chinas Zhejiang province, 16 March 2012. An investment firm controlled by the founders of Alibaba Group Holding Ltd. has agreed to buy a 20% stake in a Chinese Internet-TV company for 6.54 billion yuan, or US$1.05 billion. The investment in Wasu Media Holding Co. highlights the e-commerce company's further expansion into the digital-content market. Alibaba Group, Chinas biggest e-commerce company, will provide a loan to the investment firm to help finance the purchase, according to a statement from Wasu on Tuesday (8 April 2014), making the transaction the latest in a string of deals involving Alibaba. Wasu and Alibaba collaborated last year by jointly launching a television set-top box using an operating system developed by Alibaba. In a separate statement Tuesday, Alibaba said it would team up with Wasu to develop digital content together.
