Digital on-screen graphic

A digital on-screen graphic (originally known as digitally originated graphic, and known in the UK and New Zealand by the acronym DOG; in the US, Canada, Ireland and Australia as a bug) is a watermark-like station logo that most television broadcasters overlay over a portion of the screen area of their programs to identify 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.
