Channel surfing refers to the act of frequently changing television or radio channels, often using a remote control, primarily to avoid commercials. This practice encompasses several distinct behaviors, such as flipping (changing channels for the sake of discovery), switching (switching to a specific program), cruising (associating images between channels), switch-hitting (simultaneously viewing two programs without picture-in-picture), grazing (randomly switching between several programs), and muting (muting the sound). These behaviors reflect different motivations and ways of using audiovisual media.
