Remember, everyday is National Deals Day.
Then sometime in the 70s restaurants basically realized nobody was going to get excited about "Ground Beef Preparedness Day" and started calling it National Cheeseburger Day instead. Eventually that name just took over.
So the restaurant didn't make it up. But restaurants did basically hijack an obscure Cold War beef holiday and turn it into a reason to sell cheeseburgers.
