1- Gamma correction came from the old B&W TV days.
0-Gamma correction is used long before in printing industry (density allocation; other name, same effect).
Gamma correction is needed if your input has more colors (better: differences in brightness) as your output medium. A linear correction/interpolation is mathematical correct, but not made for human eyes.
