We had the world cup with two hosts before if I'm not wrong but still, we never had three countries in a world cup however America is the primary host and Canada/ Mexico are just helping America but I think the reason of why FIFA made three countries hosting the world cup was increasing the number of teams in the world cup that's why we need more hosts instead of one country hosting the world cup.
Yeah, that was Korea/Japan 2002, and yes, we've never had three teams hosting it.
By that logic, it would mean that from now on we will always have multiple teams hosting the world cup. Is this going to be the norm?, also, from what I've read it looks like it will be mostly played in the US.
