Most cloud-to-ground lightning (about eight of nine) is actually a rapid series of strikes, pop-pop-pop, each lasting a few hundreds of millionths of a second, too fast for our eyes to separate into individual events.

The other one in nine (give or take) creates a channel in the air, through which a lightning current can flow for much longer. In these flashes, the current can flow for tens to thousands of times longer than a normal lightning flash. While that might still be only a few hundredths of a second, this is lightning that makes things sizzle.
