it was korean teams, muyaho vs uh i dont remember

TSM vs Sentinels FaZe Invitational

T1 vs Homeless (PAX Arena Invitational) was the first actual match I've paid attention to.

Anything before that I had minimal interest in.

Pittsburgh Knights Charity Invitational was one of the first (if not the first) tournament that was pure eSports (not showmatch, twitch, etc).

This had a qualifier that started on April 18th, 2020, towards the beginning of Valorant Beta.
Qualifier was won by the 5 men team that transferred from PubG (HighGround), 4 players of which would end up on 100T alongside Hiko.

Main event was won by mSpaz by beating Highground in the final. mSpaz (mouseSpaz) was an earlier version of TSM (without Wardell and Subroza). This event final took place on April 24th, 2020.

There you go, some history lessons (:

wasn't there an invitational with pros from different games? dk if it was the first or not.
