The live broadcast room was originally a room where radio and TV stations broadcast live programs to the audience. It has a good sound insulation and silencing function, and then it is derived as a title of webcast. For example, a live broadcast room refers to a webcast opened by a person or an organization.

Live broadcast, now often called online interactive live broadcast, is a social and commercial way. The anchor uses a computer or mobile phone to simultaneously broadcast what he is doing. Viewers can watch it through websites or apps, and reward their favorite anchors or content with money to achieve an entertainment or teaching purpose.
