Why does circular pizza come in a square box?

We have ours cut in squares...;)
To Put In The Sauce In The Corner
Because it's better than square pizzas in a round box.
Because Huey Lewis sang "It's hip to be square" which probably makes me VERY square since you probably have no clue who he is!
Round boxes are too expensive.
Why do circles not have corners?

Probably for the same reason that apple pie comes in a square box !
