"Easter egg messaging" in media refers to a hidden message, image, or feature that creators intentionally embed within a piece of media, such as a film, video game, website, or software. The term is a reference to the traditional Easter egg hunt, as the messages are meant to be "hunted" for by the audience..

The practice originated in the early days of computer programming and video games as a way for developers to include their names or a secret message in products where they weren't officially credited. The first well-known example is from the 1979 Atari game Adventure, where programmer Warren Robinett hid his name in a secret room.

Key Characteristics and Purposes:

• Reward for Observation: Easter eggs are designed to surprise and delight the most attentive members of the audience. They are often subtle and require a keen eye or specific actions to find.
• Inside Jokes and References: They frequently serve as inside jokes, references to other works, or homages to pop culture. This creates a sense of exclusivity and shared knowledge among those who "get" the reference.
• Connecting Universes: In franchises, Easter eggs are used to connect different films, shows, or games, building a larger, more intricate fictional universe. This is a common practice in the Marvel Cinematic Universe, for example.
• Enhancing Engagement: By encouraging audiences to actively search for hidden details, Easter eggs foster a deeper level of engagement with the content.This can lead to online discussions, fan theories, and a stronger sense of community.
• Marketing and Viral Potential: Well-placed Easter eggs can generate buzz and go viral online as fans share their discoveries, effectively promoting the work without a traditional ad campaign.

Examples in Different Media:

• Films: Pixar: The studio is famous for its recurring Easter eggs, such as the "A113" code (a reference to a classroom at CalArts where many animators studied) and the Pizza Planet truck from Toy Story appearing in nearly every one of their movies. The Departed: Martin Scorsese's film includes the letter "X" appearing in scenes as a subtle warning before a character dies. Quentin Tarantino's films: Many of his films feature products from the fictional brand "Red Apple Cigarettes."
• Video Games: Diablo II: A long-standing rumor about a secret "Cow Level" in the original Diablo was intentionally included as a real level in the sequel. Grand Theft Auto V: The game is full of Easter eggs, including a hidden UFO at the bottom of the ocean. The Konami Code: This famous cheat code (Up, Up, Down, Down, Left, Right, Left, Right, B, A) was originally a developer's secret to give the player a boost in the game Gradius and has since appeared in many other games.
• Software and Websites: Google Search: Searching for "askew" tilts the search results, and searching "do a barrel roll" causes the page to spin. Microsoft Excel: Older versions of Excel included hidden games, such as "The Hall of Tortured Souls," as a way for developers to include their credits.
