i think the only diference is in the current level of popularity with the mainstream sports fan.
many people in serbia considered tennis boring before Djokovic was glorified in the media.
today u could say tennis is the no1. most popular sport in serbia.
and we know its popular in asia already... japan & china at least.
so its not rly different
See, what Djokovic did by winning the Aus Open, is what Borg did for Swedish tennis and Becker did for German tennis. The kids wanted to be like them and they wanted to play the game, which goes back to my point about the bandwagon effect. Those 2 nations had a big boom and big results for a while.
Now the level of depth isn't there, therefore as less success, it gets less coverage. The same will happen in Serbia, these things are cyclical, yet predictable.
Tennis isn't that popular in Japan, well not compared to football, baseball or Manga comics. Table tennis is king in China as well.
If it was that popular then there would be some more players coming through and good results from local players drives up interest.
