LeTV.com, one of the biggest online video providers in China, released a new line of low-priced Internet televisions on Thursday in a bid to achieve its 5 million unit sales goal and crush rivals.

Industry analysts said that LeTV's move will alter the landscape of the nation's emerging smart TV sector.

Selling at 2,999 yuan ($490) for the high-end three-dimensional version, the 50-inch TV is cheaper than smaller products released by other vendors including Xiaomi Corp and Alibaba Group Holding Ltd.
