Pop Photography - An introduction, perhaps?

I'm known as Rantz as well as Charles (or Charlz) Strebor - I take fotiez, I blog, I eat, I sleep and I work to pay for the first four in the list.

I haven't a clue as to what Pop Photograpy is - but I have lots of ideas.  The more I look for Pop Photography, the more confused I become and the more ideas I find tend to add to the confusion.

What is it, this Pop Photography?  Is it a subset of Pop Art - whatever that may be:


Is it photography using toy cameras or software to emulate toy cameras - whatever they may be:


Is it photography of one of those mysterious items of our current culture - the 23?


I still haven't a clue - but I still have lots of ideas (and even more confusion) about this idea of Pop Photography.  Your feedback welcome and appreciated - particularly if it adds to my confusion:
