Abstract: Disclosed is an electronic device. The electronic device may include a communication unit and a control unit. The communication unit may provide access to at least one network. The control unit extracts a search keyword from contents received through the communication unit, searches for a coupon for at least one product corresponding to the search keyword in a social commerce network, and transmits a result of the coupon search to another predetermined electronic device.

Abstract: An electronic device controlling apparatus for a mobile terminal capable of conveniently and effectively remote-control an electronic device by using a mobile terminal without a remote controller of the electronic device, and a method thereof. When an electronic device is displayed on a display unit through a camera, an electronic device identifier is received from the electronic device through a communication module. And, the electronic device is controlled based on electronic device information matching with the received electronic device identifier.
