What: Riot is building a new stadium in South Korea called LoL Park and will be taking over broadcast production for the LCK.
When: The park will open September 2018 and begin broadcast operations for the 2019 season, with plans for long term. The stadium lease lasts until at least 2029.
Where: Their arena will be in the Gran Seoul building, a location Riot picked for its public transit accessibility.
Arena Info: The arena will seat around 450. It will also have a venue for fan meets, as well as a PC café for fans.
Why they're likely doing it: If Riot takes possession of LCK broadcasting, they're able to sell broadcast rights to various media companies (for money).
Why it matters: Previously, LCK production was handled by OGN and SPOTV, South Korea broadcast channels with their own production team, on-air talent, and arena space. Fans are worried that Riot's involvement will lessen the production quality, particularly if they don't pick up OGN's beloved caster trio of Caster Jun, CloudTemplar, and Dongjun.
The good news: Riot is looking to cooperate with OGN and SPOTV. They specifically noted OGN may be able to continue their English broadcast.
