Why do movies always come out on Tuesdays?

[DavePS3]

I worked for a video distributor years ago and I'm pretty sure that when I asked the Paramount guy about that, he said something about not wanting the stuff to bee in ether over a weekend. Too much theft so everything goes on a Monday morning and either arrives later that day or on the release day, Tuesday. Rental stores are not allowed to rent before the Tuesday either. The industry needed a common date, I heard, to avoid confusion on the part of the retailer. If MGM was Thursday, Para' on Monday, Columbia on Wednesday etc... retailers would be screwing up and blaming the lax dates for the confusion so the 'hiarchy' of distribution came up with Tuesday. It was the earliest day in the week where stuff could be shipped overnight.

That's what sticks in my memory anyway.
