While the term Easter egg has been used to mean a hidden object for some time, regarding an Easter egg hunt, it is more commonly used to mean a message, image, or feature hidden in a video game, movie, or other, usually electronic, medium. The term used in this manner was coined around 1979 by Steve Wright, the then Director of Software Development in the Atari Consumer Division, to describe a hidden message in the Atari video game Adventure.
