The business world is littered with monopolies trying to block new competitors through any means possible, and one effective strategy is getting the government to intervene. This is why satellite TV couldn't carry local channels for years. It's why Southwest Airlines can't fly out of certain airports. It's why MCI had troubles using microwave repeaters to compete with ATT. And it's also why XM radio can't do local weather or sports. In each instance, the incumbent had to get a law passed or a government body to impose regulations devised to slow or stop new competitors.

They knew that this would add costs to their business - and perhaps even be unfeasible - since precisely determining the location for a computer on the Internet can be impossible.
