You forgot to mention those number are for France only. So you should say in France at domestic market RG was very succesfull, but who knows how much people watched in globally, but i think it must be one of most watched RG in history if not the most watched- each year there are more and more people with TV i think and internet - those can watch, men´s side No.1-No.4 in SF , womens´side chinese woman in final - so a lot of people watched it in PRC - i think the numbers for TV audience must be highest in history.
Yes the number are for France. The numbers domestically are the most important because out of the 47 millions that the tournament get from TV right, 16 are from France alone. It helps sponsoring too.
I think that Roland Garros is the most widely broadcasted slam in the world. But the numbers this year are really great. it shows that the interest for the tournament is growing.
