Other notable firsts—Elk Cloner was the first virus to spread via detachable storage media it wrote itself to any floppy disk inserted into the computer. But a Scientific American article let the virus out of the lab. In the piece, author and computer scientist A. Dewdney shared the details of an exciting new computer game of his creation called Core War.

In the game, computer programs vie for control of a virtual computer. The game was essentially a battle arena where computer programmers could pit their viral creations against each other. For two dollars Dewdney would send detailed instructions for setting up your own Core War battles within the confines of a virtual computer.

What would happen if a battle program was taken out of the virtual computer and placed on a real computer system? In a follow-up article for Scientific American, Dewdney shared a letter from two Italian readers who were inspired by their experience with Core War to create a real virus on the Apple II. The brainchild of Pakistani brothers and software engineers, Basit and Amjad Farooq, Brain acted like an early form of copyright protection, stopping people from pirating their heart monitoring software.
