I apologize in advance before going off topic again, just roughed out a few thoughts since the causal connection between the companies and union seems to be mixed up in the post I quoted.
KB, IBsports and KSU were complete strangers to one another when Yuna did the first commercial endorsing KB. They got to enter into a relation with one another only after they got to know Yuna through separate channel.
In the year of her senior debut, she did the first commercial, and yet she was in financial difficulties to train in Toronto, donated some part of the commercial profits for the scholarships supporting the young Korean skaters, also handed out a scholarship to her junior skaters after doing her second commercial.
Since she has been supporting young junior skaters whenever she got big money, her first sponsor KB got to know the poor domestic skating environment, and that leads to signing the sponsorship deal with KSU. If you can read this Korean article, KB official says in the interview that they got to know the poor skating environment of Korea national team through Yuna, and it is true that her advice affected their sponsorship deal.
And IB sports and KB are both involved in long track/ short track/ figure skating, and support all three sports. Though all of them became to have a relation with one another through Yuna so the skaters suffering from financial troubles could be supported financially from the big company, the system has been working without Yuna. As you can see, if you watch the skating event in the Olys, you can find KB logo in all the Korean speed/short track skaters' suits.
As for the Yuna's future career mentioned in this thread, she announced that she will not leave figure skating for the rest of her life, and wants to help Korean junior skaters and contribute to the advancement of this sport. Maybe only Yuna knows what she wants to become in the future. Interesting thing is that she is also majoring in education at the college of PE and taking a course of teaching and sports psychology, so it would be interesting to wait and see which path she will choose not in the near future but after 10 or 20 years.
Thanks for the insight. My knowledge only comes from doing some background reading, but obviously I'mlimited by my lack of of Korean (or rather no Korean skills. I only know how to say "Hello" "Thank you" and "Beer, please." )
I was thinking...maybe the mods should take our posts and put it in a thread? Like "Yuna and the role of IB Sports" or "Yuna and sports marketing companies.." And let this thread go back to being about the upcoming Hyundai show? "Probably the title should change to "Hyundai Ice Show July XXX"
