Powerpoint 2010 - Why 10" x 7 1/2" is the size?

I saw in the design tab/page setup button that the standard size is 10" x 7 1/2".
Why is this?
Why not letter size?
This seems like an arbitrary setting for page size.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Because PowerPoint was designed for presentations -- for screen, not for print, and most screens are (or were at one time, anyway) 4x3. 10" x 7.5" is 4x3 ratio.

We're moving into a wide-screen world, though, and PowerPoint 2013 reflects this with its new slide size: 13.333" x 7.5", which is a 16x9 ratio. (Here's a little more on that: http://echosvoice.com/size-matters/ )
