For example, the Observer newspaper reported that a software company had launched a programme which would "sniff out" and delete more than 4,000 different games commonly stored on the networked systems found in offices and universities.

The program renders obsolete a built-in defence system - the "boss" key - incorporated into most games, which is designed to hide what the computer user is up to. When anyone in authority approaches, it is pressed to remove the game from the screen and replace it with a fake spreadsheet or business graphic. (17/3/1996, p5 of the main section)

Portsmouth University, one of the first organisations to use it, found 140 illicit games being stored and played in one faculty alone.
