on TVs actually serve a purpose, as I just learned. It is a test pattern for calibration purposes. Engineers actually still use it today in order to adjust the color schemes so that each television that is manufactured will align with the standard. That's pretty nifty! I rarely saw them as a kid. I grew up with 24-7 television, so the whole nightly sign off thing wasn't part of my experience.
