The NHL easily qualifies as a major sports league, because of the average attendance of the teams, television ratings, and media coverage of the events.  Its popularity in Canada alone qualifies it.  And everyone, please help spread the attitued of ignoring trolls (like people who say Hockey is a children's sport).  They are clearly looking for a reaction.  I also want to say that there needs to be a lot more emphasis on the major football (soccer) leaugues around the world, because right now, the article seems to be too slanted towards us leagues.  The problem is not too much info on the Big Four in the US (it is excellent), but too little information on the soccer leaugues.  Information about cricket, wildly popular in certain parts of the world, should also be included.  Otherwise, I propose that the title of this article be changed to "Major US sport leagues"
