How can the physical size of an average USB stick stay the same (or even decrease) while storage capacity rises over the years?

Question

When you go to the store to buy an USB stick the storage capacities of sticks are much larger than those you would find in the same store 10 years ago. However, the physical size of today’s USB sticks is about the same (or even smaller) as the sticks from 10 years ago. How?

Answer 1

Most of a USB stick is just empty space, so there’s actually plenty of room to stick more stuff inside.
