And? That has nothing to do with the definition of a monopoly. You can have a monopoly in any industry, and there are many reasons why they can form. In most industries, when monopolies form, they occur because one company outperforms the competition to such a degree, sometimes due to predatory practices, that the end result is a single provider. Usually when that happens, the company is forced to split up into multiple companies.
In the case of utilities, past lawmakers have deemed them to be what economists call a natural monopoly, meaning that the market forces for that industry favor a single provider to such a degree that consolidation is inevitable. In such instances, lawmakers have allowed the monopoly to remain in existence, but provide governmental oversight to prevent abuses like price gauging, etc.
My personal opinion is that sports leagues are a form of natural monopoly, as fans tend to favor a single professional sports league for any given sport. The fate of competing leagues in the past that have tried to challenge the NFL, NBA, and NHL would tend to support that theory. They have all either ended up merging with the existing league, or have gone out of business.
