From the "evolutionary history" of WeChat, payment functions, public platforms and mini programs are the three nodes in the evolution of WeChat products. Will content payment be the next evolutionary node? Three years later, it's here... will it go in the future? On January 15, WeChat officially announced that the WeChat public platform is currently testing the subscription account payment function in grayscale. According to reports, personal accounts registered for more than 3 months, no serious violation records within 3 months, and published at least 3 original articles may be selected by WeChat to become participants of this test. After obtaining the qualification for the grayscale test, the subscription account "Three Tables Longmen Array" published an article entitled "Thousand-character long text tells you how to make money by paying for WeChat reading". On the one hand, it intuitively interprets what opportunities the subscription account charging public can bring, and on the other hand, it is also a test of the paid function. In addition to the three tables, Internet technology critic Chi Jianqiang also published an article titled "How sms marketing service Individuals Make Money on the Internet" on his subscription account "MacTalk" to test the paid functions and effects of WeChat subscription accounts.
