pizza, pizza

I came, I saw, I ate pizza...

One striking difference between the emergence of "pizza"
in M&D and the basic pizza as most of us know it, is that Dixon's
version is more complex than the basic cheese, tomato sauce
and crust pie.

Could this be a suggestion that some very successful cultural
artifacts start out more complex and gradually become less
so as they evolve, contrary to the tendency to assume that
such processes are ever increasing in complexity?
