History
Dota 2
Foundation and early success (2015–2017)
OG was founded as "(monkey) Business" by players Tal "Fly" Aizik and Johan "N0tail" Sundstein, who were former Team Secret players, along with David "MoonMeander" Tan, Fritz "Frtz" DG, and Andreas "Cr1t-" Nielsen in August 2015. Soon after a dominating run through the European qualifiers for the Frankfurt Major, they adopted the moniker OG. They went on to win the inaugural Dota 2 Major Championship in Frankfurt in November 2015, earning US$1 million in prize money. Despite placing in the bottom half of the next Major in Shanghai in March 2016, the team would rebound and take first place at the Manila Major in June 2016, becoming the first team to repeat as champions of a Valve sponsored Dota 2 tournament.
OG entered The International 2016 as one of the favourites after earning a direct invite, but ended up finishing 9-12th out of 16 teams. In August 2016, MoonMeander, Miracle-, and Cr1t- left the team, with Gustav "s4" Magnusson, Anathan "ana" Pham, and Jesse "JerAx" Vainikka replacing them. Despite the new roster, OG won the Boston Major in December 2016, giving them their third Dota 2 Major championship. For the first premier tournament following Boston, OG advanced to the grand finals of the Dota 2 Asia Championships in Shanghai, where they were swept in a best-of-five series against Invictus Gaming.

Why this record matters
“OG (esports)” is worth following because a concise public description often conceals a longer documentary argument. Here, esports, professional and organisation provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 22, 2026. The linked authority identifier is Q25223187. 1 of 2 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2015, 2018, 2019 and 2017.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
