• There are areas using what's called the "checkerboard strategy." They are different cities where you can move around the "checkerboard," doing things you can't do in every square, that you can do in some of them, building a mosaic of these kinds of practices. There are about 400 cable television networks, for example, that are publicly owned. That's a big fight for big private companies. In some areas, this is a political struggle, in some it's conventional common sense.
