2017 League of Legends World Championship

The 2017 League of Legends World Championship was an esports tournament for the multiplayer online battle arena video game League of Legends. It was the seventh iteration of the League of Legends World Championship, an annual international tournament organized by the game's developer, Riot Games. It was held from September 23 – November 4, 2017, in cities across China. Twenty four teams qualified for the tournament based on their placement in regional circuits such as those in North America, Europe, South Korea, and China, with twelve of those teams having to reach the group stage via a play-in round.

The finals featured a rematch of last year's competitors, and in 2017, Samsung Galaxy secured their second championship win after defeating the three-time world champion SK Telecom T1, with a 3–0 sweep in a best of five final series. Samsung has previously won the 2014 League of Legends World Championship. Park "Ruler" Jae-hyuk, the AD carry of Samsung, was named the MVP of the tournament for his outstanding performances.

Against The Current and Jay Chou collaborated with Riot Games to produce two exclusive songs titled "Legends Never Die" and "Hero" respectively for the tournament, while Alan Walker also produced his own remix of "Legends Never Die".

The 2017 World Championship was praised for its ceremonial performances, while receiving attention worldwide due to the high quality of the tournament, its multiple dramatic and emotional series,    and SK Telecom T1's tributary moments. The finals was watched by 60million unique viewers, breaking 2016's viewer record. A donation of US$2.35million was also raised through the sales of Worlds 2017 Championship Ashe skin.
