I do think if the American team actually did well, which they never do, Olympic Taekwondo would be well received. Aside from the Lopezes, which Americans have won medals? Your typical American viewer isn't going to tune in to see his countrymen lose. The Koreans watch because they know the Koreans will clean up.
OK, let's see. TKD was introduced to the Olympics in 1988 as an exhibition sport. All 8 weight divisions were used and each country could send 1 male and 1 female athelte per division.
I am not sure if the USA sent all 16 that they could or not, but 11 did medal
1988 Jimmy Kim - Gold
1988 Lynnette Love - Gold
1988 Dana Hee - Gold
1988 Arlene Limas - Gold
1988 Debra Holloway - Silver
1988 Juan Moreno - Silver
1988 Mayumi Pejo - Bronze
1988 Han-Won Lee - Bronze
1988 Greg Baker - Bronze
1988 Jay Warwick - Bronze
1988 Sharon Jewell - Bronze
In 1992 TKD remained an exhibition sport. Again all 8 weight divisions were used but coutries were limited to 3 male and 3 female athelete per country.
The USA sent their maximum of 6 and all 6 picked up medals
1992 Herbert Perez - Gold
1992 Juan Moreno - Silver
1992 Diane Murray - Silver
1992 Jennifer Laney - Bronze
1992 Terry Poindexter - Bronze
1992 Lynnette Love - Bronze
In 1996 TKD was excluded from the Olympic games.
In 2000 TKD became an offical recognized sport in the Olympic games. The 8 weight divisions were combined into 4 and countries were limited to a max of 2 male and 2 female athletes per country.
The USA sent their max of 4 and only 1 medaled.
2000 Steven Lopez - Gold
In 2004 the rules were the same as 2000.
The USA sent 2 athletes and both medaled.
2004 Steven Lopez - Gold
2004 Nia Abdallah - Silver
With the exception of 2000, the USA has not done all that bad on the TKD Olympic stage.
