Why did flyers get smaller?

I made an earlier post about size o flyers in the early 90's getting bigger and bigger. But what is obvious is that after a certain period the began to get smaller again. Now I am sure their was an element of cost saving on the printing involved but that doesn't fully explain things. The reality was that it was very expensive to transport and hand out large flyers. New methods were evolving to reach clubbers. Companies like Out of Hand were formed who gave out flyer bags containing many rave companies flyers and other stuff all at the same time. This was cheaper and easier for them and also for the promoter. The limitation was the size of the bag, this was normally less than A5 in size.

I like the flyer bags when I get them as they contain so much however they do lack that feel and I do miss the large ones that would look great on your wall, these little ones just dont compare for that.

Does Size matter?

As the rave scene evolved and I guess printing got cheaper, rave flyers went from A5 to A4 to A3 and then to designs with many pages or folds. Which ones do you prefer? I think the A3 ones have the most impact, but were easily damaged when collected at the end of the night. Plus they don't fit in any of my filing systems as they are so large.... A4 are perfect IMO. A5 just a little to small to get that visual impact...
