Everything else is simply not on TV except for olympics/pan am games.
This is strictly about popularity/TV ratings. If it's about participation numbers the scene changes a bit (for ex. Gymnastics has a good number of people that practice).
There are also sports that are popular in particular regions or provinces.
Examples: Rink Hockey in San Juan, Cycling in the west/northwest in general, Softball in Entre RÃos, Ski in the south, etc.
As I mentioned in page 4 the official national sport is Pato, but it's virtually unknown among the general public and doesn't have any TV coverage.
