Now that I mention it, you don't know, do you? 

Neither did I. I was trying to figure out what the letters could stand for and came up with nothing. Everyone just knows the famed celebrity website as TMZ. So what does it stand for?

I was shocked...

Thirty Mile Zone. Yup. Who'da thunk it?

It's named after the historic "studio zone" centered at the intersection of West Beverly Boulevard and North La Cienega Boulevard in Los Angeles.

And now you know :)
