People think about it for one direction and not think about it for the other direction. What happens when Americans or Canadians or Mexicans wanted to watch the games? Not like these three nations combined make a little amount, we are talking about hundreds of millions of people, and when it was at Qatar, you think they all watched at prime time? Of course not, they watched it at horrible times, either very early in the morning or even at night after midnight as well.
This means that when you make it on the east, it is good for east but bad for west, when you make it further west, then it is bad for east. You have to just realize that one way or another, you are going to make some parts of the world not watch it at ideal time zone, that's just the reality. But they may make it at proper hours to get it at least to a decent time.
How many people live in the western hemisphere by the way? Out of a total global population of almost 8 billion, only around 1 billion people (13%) live in the western hemisphere. So do you believe that it is ideal to give priority for this 13% over the remaining 87%? BTW, I am not forgetting the fact that some of the top teams hail from the western hemisphere (especially Argentina and Brazil). I just hope that the FIFA will schedule the matches in such a way, that people residing in Asia and Europe will be able to watch them without going through the pain of going without sleep.
