Wow, I think you are greatly underestimating how big of an impact Jordan had. Maybe basketball is not a popular sport in your country, but millions of people around the world are invested in it. And Michael Jordan was the biggest name in basketball in the 90s. People were very invested in his performance as an athlete because he led his team to 6 titles. He was more or less the perfect player, a symbol of success. Every kid throwing a basketball on a rundown court in the world dreamed of being Michael Jordan. He also had very successful endorsements (mainly with Nike) that, as I posted above, result in him being the biggest earning retired athlete to this day (and he starred in Space Jam, as analogue said :beee::lol
. With regards to the bolded part, I don't quite understand why you say that, because you said yourself that a big part of Beckham's fame had to do with him being known for things outside of his performance on the pitch. So if anything, people were not as invested in
his athletic performance, right?
You're absolutely right that football is huge and that you'll see kids in the most remote villages in Africa wear football jerseys. But I think these kids relate more to the player's performances, rather than the celebrity gossip that dominates the tabloid press here. I don't doubt that many of them know Beckham, but that would be for his performances as a player, not because he married 'Posh Spice'. And there are many players who had more success on the pitch than Beckham. Beckham is obviously a massive star, but we are talking about worldwide fame here, and I have serious doubts about his cultural impact in the non-western world. I also think that, because he was not the most successful football player there is and because his fame has to do with a lot of external factors, his longevity now that he has retired will be a lot shorter than Michael Jordan's, who remains relevant because he is still seen as the greatest basketball player of all time.
Well anyway, at least we agree on one thing: that neither of these guys are more famous than MJ.
Sorry for straying offtopic.
As for the most famous American athlete, Jordan is a good candidate. Muhammad Ali would be another.
