The term 'Easter egg' in software comes from a literal act of defiance against corporate IP control.
Warren Robinett spent a year cramming Adventure into 4KB of Atari 2600 ROM—pioneering the action-adventure genre—but Atari refused to credit him on the box. Their logic: if competitors knew who built the hits, they'd poach the talent.
So Robinett hardcoded his own credit. He created a 1-pixel object (the 'Gray Dot'), placed it deep in the game's maze, and programmed a sequence: carry the dot through the catacombs → bring it to a specific corridor → walk through a solid wall → enter a hidden room with flashing text: 'CREATED BY WARREN ROBINETT.'
He submitted the final ROM and quit immediately without telling anyone.
A year later, a 15-year-old kid in Utah found it and wrote to Atari. Execs were pissed, but remanufacturing physical cartridges was too expensive. They spun it as an intentional 'Easter egg hunt' feature to save face.
The term stuck. Every hidden dev credit, secret level, and cheat code since then traces back to one programmer's refusal to be erased from his own work.
