No, I'm not talking about these Easter eggs, I'm talking the other kind of Easter eggs.

In the media, "Easter egg" is a term used to describe a message, image, or feature hidden in a video game, film, 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, in reference to an Easter egg hunt.
