The advance of digital information technology，not only has brought the birth and development of the new media industry，but also created a vast amounts of data. Traditional data processing technology is not very good to deal with storage and calculation of mass data，so people invented the new technology to cope with the challenges，and its name is Big Data.

Development of the new media industry also brought a lot of data，and Big Data technology is eager desired. The new media industry has found a new development area during usage of Big Data technology，includes real-time advertising system，audience interest mining，and data journalism. These new media field not only brings consumers much more media content and better consumption experience，also has brought the new media industry more output value and profit.

BAT，the big three of China’s new media industry，have most application and contribution on Big Data technology. However，compared with foreign’s top companies such as Amazon and Google，our technology is not much advanced. Lack and backward of technology will bring the new media industry security risk，and restricts the development of the industry too. On the contrary，if we can catch opportunity of big data development，develop new technology of Big Data which is based on Chinese national conditions，we will be able to get rid of the dependence of foreign hardware and software，and master the core technology by ourselves.
