What Is 2016 Mid-Season Invitational

Overview

The 2016 Mid-Season Invitational (MSI) was the second annual international League of Legends esports tournament hosted by Riot Games. It brought together top teams from major regional leagues to compete for global supremacy midway through the competitive season.

Hosted in Shanghai, China, the event ran from May 4 to May 15, 2016, and featured an expanded eight-team format. This edition introduced a new group stage followed by a knockout bracket, increasing competitive depth.

• Eight teams participated, representing regions including Korea, North America, Europe, and China, each qualifying through their respective Spring Split championships.
• SK Telecom T1, the LCK Spring 2016 champions, entered as favorites and remained undefeated throughout the knockout stage.
• Counter Logic Gaming represented North America after winning the NA LCS Spring Split, becoming the first Western team to reach the MSI final.
• The group stage used a double round-robin format, with the top four teams advancing to the semifinals based on win-loss records.
• Shanghai Oriental Sports Center hosted the final weekend, drawing thousands of live attendees and millions of concurrent online viewers globally.

How It Works

The 2016 MSI followed a structured format that combined round-robin group play with single-elimination playoffs. This design allowed for both consistency and high-stakes drama in determining the world's best mid-season team.

• Group Stage: The eight teams were divided into two groups of four. Each team played every other team in their group twice in a best-of-one format. The top two teams from each group advanced.
• Double Round-Robin: This format ensured teams played six games each during groups, testing endurance and adaptability over multiple days.
• Playoff Bracket: The semifinals and finals used a best-of-five single-elimination format, increasing stakes and intensity as teams neared the title.
• Regional Representation: Only one team per region qualified, based on their performance in the Spring Split, ensuring true regional champions competed.
• Champion Rewards: The winning team earned a cash prize and international prestige, bolstering their legacy ahead of the World Championship.
• Global Viewership: The event peaked at over 3.5 million concurrent viewers during the finals, highlighting its growing esports significance.
