Show bibles, especially in scripted television, are added to all time, and they are crucial. If the script would mention a character's mother by first name, a writer would consult the bible to see if that name was ever established. If not, whatever name is used is added to the bible. Some showrunners have found recently that their fanbase sometimes adds far more detail to the Wikipedia articles about the series than the bibles.
In this case, I would assume that there was a story that involved the game show scandal either directly or indirectly, and so when it was quashed, they made a note in the bible for future reference.
