What is tv static?

TV static, also known as snow or electronic noise, is the random flickering or flashing distortions on a television screen when no signal is being received. This phenomenon occurs when a television is not tuned to a specific channel or when there is interference in the transmission of the signal.

TV static appears as a pattern of dots, lines, or shapes that continuously change and move across the screen. It is typically seen on older analog televisions, rather than modern digital televisions. The cause of TV static can vary, including weak reception, a faulty antenna, or electronic interference from nearby devices.

While TV static is often considered an annoyance, it has been used in various forms of media for artistic purposes and as a visual effect in movies or television shows. Static noise can evoke feelings of nostalgia, mystery, or suspense in certain contexts.
