In fact it's both.  A slow, weak `leader' makes its way from the clouds to the 
ground.  This sets up a number of return strokes, from the ground up, at 
intervals of about a tenth of a second.  This is why you see quick flashes.

There's a device (can't remember its name) to photograph this on a rotating 
piece of film.  Also, electricity may travel near the speed of light, but 
lightning doesn't.

Gigavolts!
