This application is directed to enabling interaction between computer devices. An application is executed at a first computer device to access Internet-based media content sources and display media items provided thereby on a display device coupled to the first computer device. The first computer device transmits an information item and a command to a second computer device. In some implementations, the information item includes a selectable display element corresponding to one of the Internet-based media content sources, and the second computer device is configured to display the selectable display element of the information item. In response to a user selection of the selectable display item at the second computer device, the first computer device receives the command from the second computer device, and executes the command in relation to the Internet-based media content sources.
