The data support the operation of the media. What we browse from the different media is according to the past research records and information we shared online, which is the reason that we always can see what we want to see and get the information we want in a short time. From the Data’s perspective, we are just small points of our interests. It will form data images and then be categorized into different groups. This is the reason why we think the internet knows us so well. It is convenient since you can always browse things you want. For example, when you download a song you like, the app will soon send you lots of songs in that genre, which can help save a lot of time. Moreover, you can also learn more about yourself from data by using media. You can know how much time you spend on each media, and what kind of things you like from your recommendation pages. However, at the same time, privacy leakage is a big problem. Selling personal information online is a huge part of internet operation. This is the way how companies find their “target consumer”, which is easier for them to market their products. What’s more, people’s locations, chatting records, private photos become data for some purposes. How to solve power asymmetry on social media is the problem we need to think about.
