In my opinion, the MBC commentators showed just as much energy as the Spanish, even though a plague means far less for the MBC staffs than a goal in the 115th minute for the Spanish.
However, the point of this blog is not just about posting two youtube video and asking the readers to compare the volume. The point is that in my opinion (e-)sports are exciting to watch at least partially because the commentators yells out of "excitements" - that is, when the commentator sounds excited, you become excited too.
I think this is similar to how laugh track works. In case you are not familiar, laugh tracks are pre-recorded sound that gets played in TV shows right after a joke is told (e.g. Friends, Big Bang Theory, etc. use laugh tracks). While some sources say laugh tracks give cues about when to laugh to the audience in front of the TV, I believe it's a conformity effect - when you think other people are laughing, you think it's funny too, or perhaps even funnier than if the laugh track was not played.
Just a random thought. Thanks for reading.
