"DOG" redirects here. For the animal, see
dog. A digital on-screen graphic (known in the
UK and
New Zealand by the acronym DOG; in the
US and
Canada as a bug; and in
Australia as a
watermark) is a watermark-like station
logo that many television broadcasters overlay over a portion of the screen-area of their programs to assist viewers in identifying the channel. They are thus a form of permanent visual
station identification, increasing
brand recognition and asserting
ownership of the video signal. In some cases, the graphic also shows the name of the current program. Some networks use an on-screen graphic to advertise later programs in the day's television schedule—this is generally displayed after the opening, during in-programme credits, and when returning from a commercial break. Usually in United States sportscasts (such as on
CBS and
NBC), the "bug" is moved to the top-right corner of the screen.
