They don't have to. You can initialize them to any "constant" value (for a peculiar value of "constant"); zero just happens to be the default. — tc., Aug 06 '10 at 16:39
You can initialize a static variable to something other than zero in the declaration if you wish. — semaj, Aug 06 '10 at 16:39

This required for a compiler to conform to the C standard.

The reason for the design choice is likely that having random garbage in your uninitialized variables makes errors much harder to detect.
