In e-commerce activities, the effectiveness of information exchange is directly related to the success or failure of e-commerce. The release of commodity information is an important information behavior of businesses in e-commerce activities. Streaming media is one of the important forms of information release in e-commerce activities. Streaming media can simplify the information of e-commerce activities and make people to know the information clearly. It can present big data information to customers in time and save the delay of big file transfer. But it still has some security technology problems.As it is not directly contacted, the product may be counterfeited. In addition, due to the low cost of streaming media, there may be business fraud, resulting in customer losses. In my opinion, although it has some problems, in the current era, streaming media has indeed become the mainstream of e-commerce, and it does have an important position in e-commerce. I personally support the development of streaming media.
