When I was growing up in Massachusetts, the Boston Globe basically owned the coverage of the Massachusetts sports teams. Now ESPN has a whole Web site devoted to Boston sports, with articles like this long piece by Howard Bryant on the struggles of Red Sox slugger David Ortiz. At any point during my youth, some government regulator could have stepped in and said, you know what, the Globe has too many of the best sportswriters, and too much of a market share of sports news, and we are going to intervene break it up. But they didn't. And what happened? New competitors entered the market. Sometimes what seems like a position of unassailable market dominance is eroded not by regulatory intervention but by time and free-market competition.
