The Olympics: how much does a country's coverage of the events emphasize their own strengths as opposed to the overall offerings? I particularly wish to hear from non-Americans?

I notice that US coverage emphasizes sports in which we excel [like swimming events] or that we invented [like beach volleyball or basketball].

The Olympic competition is huge, and many events occur simjltaneously. But I see little of such things as track-and-field or curling or many other events. Do those from other countries see a different offering?
