It is 2018 and this error message is a mistake from 1974.

When this was developed, nothing had UPC codes yet because they'd just been invented.
Back when this mistake was made, There was only one Phone Company, because they hadn't been broken up yet. Ted Bundy was still on the loose. Babe Ruth's home run record was about to fall.
When this bug was developed, Wheel of Fortune hadn't yet aired. No one had seen Rocky Horror. Steven Spielberg was still a little-known directory of TV films and one box-office disappointment. SNL hadn't aired yet. The Edmund Fitzgerald was still hauling iron ore.
WHEN THIS STUPID MISFEATURE WAS INVENTED, THE GODFATHER PART II HAD JUST OPENED IN THEATERS.
