Why Is a Black Box Called a Black Box?

Answer

The term black box entered the English language around 1945, which referred to the process of network synthesis from the transfer functions of black boxes. This system or method, which was described as black-box analysis by others, is traced to Wilhelm Cauer who published his ideas in their most developed form in 1941. A black box is a system which is viewed in terms of its output, input and transfer characteristics and without any knowledge of its internal workings, which is black.

The early flight data recorders were mostly painted black, and were often referred to as Black Boxes. The phrase stuck and although in the early 60’s they were now painted bright orange or bright yellow to make them easier to find at a crash scene.
The reason a black box is referred to as such is because it records data without any knowledge of its internal workings to a person observing it and not due to the colour. Blackboxes are used mainly in aircraft as flight recorders.
