The Season 3 World Championship was an esports tournament for the multiplayer online battle arena video game League of Legends.

SK Telecom T1 defeated Royal Club 3–0 in the finals and took their first championship.

These numbers were much higher than those of other competitor eSports events for Dota 2 and Starcraft 2, the former of which only reached one million concurrent viewers.

League of Legends is by far the biggest entity in the pro-gaming sector, regularly outstripping the stream viewer numbers of its major competitors, including Valve's Dota 2 and Blizzard's StarCraft II.

In context, Valve's flagship Dota 2 tournament — The International 3 — took place two months before the League of Legends Season 3 World Championship finals and reached one million concurrent viewers.
