New Comic Day Unique?

I understand that other industries also have specific days when their new products come out (CDs, DVDs, etc.)...but is there another industry that has anything similar to the comic book industry's "New COmic Book Day," where the day is almost treated as a mid-day holiday?

I think new DVDs (Tuesday) is probably the closest, at, say, a Blockbuster. People showing up to rent the newest releases. But even that is not exactly the same.

Is there a better comparison that I am missing?
