A method of facilitating an operating terminal to control media information displayed on target terminals using a computer server is disclosed. Upon receipt of a search request for target terminals within a local area network from an operating terminal, the computer server identifies a list of online terminals as the target terminals and returns the target terminals to the operating terminal. A user of the operating terminal then generates an operation instruction for controlling media information displayed on the target terminals. In response to the operation instruction, the computer server sends the operation instruction to respective applications running on the target terminals. The respective applications are configured to control the media information displayed on the target terminals in accordance with the operation instruction.
