Why is the format of the VGC Doubles?

I have always wondered why the VGC is played in doubles and not in singles. I mean, 99.99% the battles in the games are singles and even things like Showdown use singles as the primary format. So, why does the VGC happen in doubles?

There are two main reasons.

No matter how broken a strategy/pokemon/set it, it will be always more manageable in doubles, because you can always outplay with protects and double targeting. A frail and fast set-up sweeper in singles has effectively infinite health, as long as it keeps OHKO’ing stuff. That will never happen in doubles. It is, therefore, easier do design for doubles, because there is more room for error.

and

Not only is doubles faster and way more balenced but there’s a lot more strategy behind double targets and protects other then in 1V1. Considering your only means of protecting yourself or getting yourself in a safe position in singles is to switch, it makes it so switches are played more than actual attack.

Additionally, it is much faster.

If you see it from an organizer point of view you can’t afford that a 150 people tournament goes for more than one day, my point being, games in singles are way too long. Sure when two hyperoffensive teams face each other things go rather fast, but bulky or stall teams are something else.
