Belisarius Productions is the television production company founded by producer Donald P. Bellisario, the creator behind series such as Magnum P.I., Quantum Leap, JAG and NCIS. Its closing logo became a routine part of broadcast viewing for decades, seen and heard after the story had ended and the credits had run. Online, that familiar end card moment has been lifted as a standalone clip, shared by fans who recognise the sting instantly and reuse it whenever they want a proper, old school television sign off.
