In the USA, American networks such as Showtime and HBO generally ignore and/or simply refuse to broadcast talented white boxers based in Europe. In the 1990's, something like 60% of championships in boxing would be held by American fighters, today that number would be down to only about 25% of championships being held by Americans. Boxing as a sport is simply gravitating away from American Negroes. Amateur boxing tournaments going on today also indicate that the sport is becoming further European and Asian dominated. Boxing as a sport has no future in USA.
I once made an estimate a few years back, that because Americans are getting worse and worse at this sport, there would be a day when HBO Boxing dies, and the network stops showing boxing. I feel that day is coming sooner rather than later (HBO has recently had some friction in past months and lost a lot of market share). Boxing has no future in the USA and the fighters it is producing these days are simply not very good because competition levels have increased. What will HBO do when there are no American Negro champions? Who will they show then? Today there's what only 7 or 8 American Negro champs (Broner, Ward, Mayweather, Hopkins, Trout, Smith, Bradley, Alexander) out of a possible 68 (17 weight classes, 4 titles per weight). Give it another 10 years and there will only be 2 or 3. Americans have lost all ground in this sport and that is only going to keep accelerating. 15 years ago, there would have been 20 or so American Negro champs.
HBO did show early parts of Klitschko's career (such as his knockouts over Negroes Byrd, Brock, and McCline), but in roughly 2008 or so, HBO began a censorship on the white dominated heavyweight division. This censorship of talented white athletes (not just the Klitschko's but many talented white fighters such as Kessler, Froch, Huck, Povetkin, Bute have been largely ignored by American networks) is in many ways parallel to American news media's censorship on black-on-white crime. Both forms of censorship by American media have a white self hating, black worshipping bias.
That being said, I think most Americans who follow sports are aware that Klitschko's run the heavyweight division in spite of this censorship. The good news, though, is that in Europe, the Klitschkos are mega stars and have sold out 60,000+ seat arenas. Klitschko's win over Haye had 60,000+ people in attendance and it has been said that it is the most watched boxing match of alltime. No boxer in the USA comes anywhere close to that level of stardom. The Klitschko's are well known by pretty much everyone in Europe, and truthfully, their fights are bigger than any in the USA. So, while the Klitschko's have been largely censored in USA, on the contrary, in many parts of Europe they are huge celebrities.
Americans talking about Tyson are dreaming about past times, quite pathetic actually. Maybe they wish they had a time machine to go back to the 1980's when the sport was just an American sport. Maybe you should tell them to research "time travel". lol...
