Overwatch initially showed promise for an esports scene during its beta phase in 2015, attracting teams from around the world to compete upon its full release.

The league faced challenges early on, including a slow start in its inaugural years and logistical issues exacerbated by the COVID-19 pandemic in 2020.

Additionally, the announcement of Overwatch 2 in 2019 brought about changes to the game's format and gameplay, which received a lukewarm response upon release in 2022.

These challenges, coupled with controversies such as the sexual harassment lawsuit in 2021, led to mounting pressure from teams to exit the league.

Months before Microsoft's acquisition of Activision Blizzard, teams were offered the chance to leave the Overwatch League, ultimately leading to its closure in January 2024.

From there, the top teams from each region advanced to the OWCS Asia Championship, an eight-team event held at the WDG Esports Studio.

Circuit points were awarded to top finishers in the Main Event, determining qualification for international tournaments.

In Asia, the broadcast was available on platforms such as YouTube, CHZZK, AfreecaTV (Korean), and Twitch (WDG and PlayOverwatchJP for Japanese audiences).

Viewers could earn exclusive in-game rewards, such as OWCS-themed cosmetics, through Twitch Drops during official match streams.
