Abstract: An electronic device includes a detector configured to detect a user input and a controller configured to determine a favorite channel group according to a user's viewing history, scan channels in response to detecting an input of a control signal corresponding to a channel shift button for a predetermined time, and decrease a channel shift speed in a favorite channel group section corresponding to the determined favorite channel group and increase the channel shift speed in a section other than the favorite channel group section.
