Splitting companies that have physical presence is something that is a bit easier to do? That is, my gut would be that the examples you have in your mind for how companies that hit market dominance were split, are dominated by markets that required a bit more physical connection to the consumers they were serving.

You could also see easy ways to force a company that is using a dominant position in one industry to gain an upper hand in another to divest from that expansion.

Most of that falls apart with the nature of these markets, though?
