DVDs are the same size as Cd's. So why is the size of the packaging different?

As we can see in our house, super market etc, the difference between this two packet is always the same, do we know why does it look like this?

Probably this situation is just because that DVD’s needs an advert on the packet, we can say that CD’s need it also, but less than a DVD’s packet- they have more pictures, information etc.

In the other hand, we can say that the “history” concerned different size of the packaging was created several years ago and this is just a tradition.

If we will look at this from an economics point of vieu, we could say that it is just a wonder to growth the gain.

Why do most popular book's and CD's sell for less than the least popular book's and CD's but we see the opposite in the cinema price.

In our days the number of peoples who goes to the cinema have growth, probably just because of that our society is more humanistic, or just want to be. So I think that is normal that cinema launching to growth the price of the ticket.

If it is concerned about books and Cd's, the demand for them is smaller. Today if I want to hear a special kind of music, a CD of a band which do I like, I can take it from the net, there are lots of special site from where do we can downland them. The another thing is with books, if they are popular, they are project in the cinema, so more of society don’t need at all to buy them. The opposite is with least popular book, because people want to read it, so the sell for them growth.
