@dsspredator: More people than you might think. If you're on sat. or cable you can still watch most channels in SD if you want to. The old TVs can still be hooked up through legacy connectors to most modern TV boxes. I've even heard of people who have new HD sets who still watch the SD channel instead of the HD equivalent. They just don't see the need to change their long standing habits or memorize a new set of channel numbers.
