The ASL is a StarCraft: Remastered tournament in South Korea, hosted by SOOP, a video streaming service. The tournament was originally called the AfreecaTV StarCraft League (Korean: 아프리카TV 스타리그), then the SOOP StarCraft League (SSL), and is now known as ASL. It started its first season in June 2016 and used StarCraft: Brood War for the first three seasons before StarCraft: Remastered was released. The tournament is regularly broadcast in Korean on SOOP. Dan "Artosis" Stemkoski and Nicolas "Tasteless" Plott provide English rebroadcasts on SOOP's YouTube channel.
In 2018 and 2019, the ASL ran alongside Blizzard Entertainment's Korea StarCraft League (KSL) as one of the top-level Korean leagues for StarCraft: Remastered. On March 20, 2020, Blizzard stopped the KSL tournament series, making ASL the only top-level Korean league for StarCraft: Remastered.
On July 25, 2024, the tournament changed its name to SOOP StarCraft League (SSL) to match the rebranding of AfreecaTV to SOOP. The tournament's naming format also changed, with the first season under the SSL branding called SOOP StarCraft League 2024 AUTUMN, starting on August 26, 2024. The name was changed back to ASL for the next season.
