It depends on what you mean with OOP. If you mean the original meaning: just messaging, extremely late binding, hiding the state etc. OOP never took off.
The established meaning is using classes as some kind of abstract data type with getters and setters or using classes interfaces. That kind of OOP is usually supported.
