Fnatic (Season 1)
During Season One, the LoL World Championship was still budding, and it lacked meaningful infrastructure in place. Consequently, Riot Games chose DreamHack Summer, Sweden, as the event venue. In this event, a total of eight teams participated- three teams from Europe, three teams from North America, one from the Philippines, and one from Singapore. Fnatic, a Swedish team, got the better of its opponents, defeating Counter Logic Gaming 2-1 before sweeping Epik Gamer. Fnatic faced Against All Authority in the Grand Finals, making the Season One Finals an all-European affair. They would take home $50,000.
Taipei Assassins (Season 2)
The event was held in Los Angeles, California, and it has a $2,000,000 prize pool that was forty times the maiden prize pool. Following the completion of the Group Stage, TPA was pitted against the Korean NaJin Sword team. Surprisingly, this Taiwanese team swept NaJin easily, advancing to the Grand Finals after a high-octane 2-1 victory over Europe's then top-ranked Moscow Five. Taipei were pitted against Azubu Frost, Korea's top seed, who they effectively shut down. They won the contest 3-1, bringing the first-ever World Championship crown to Taiwan.
SK Telecom T1 (Season 3)
Season three was the first time in Worlds history that a series went all five games. SKT would eventually defeat NaJin to advance to the Grand Finals. However, the match versus Royal Club was a letdown, as SKT thrashed them 3-0 to win Korea's first championship. This victory marked the beginning of Korea's dominance in the championship.
Samsung White (Season 4)
The duel between Samsung White and Star Horn Royal Club ended in a 3-0 thrashing. In this match, the loser managed to win only one game. It was the first championship win for Samsung White and Korea's second in a row. Royal Club, currently known as Royal Never Give Up, is the only team to have finished as runners-up in the tournament on multiple occasions.
SK Telecom T1 (Season 5)
SKT faced the KOO Tigers in the Grand Finals of 2015. This was the first of three consecutive all-Korean Worlds finals. SKT's perfect Worlds run was ruined by the KOO Tigers, who managed to win one game, but that was the best the latter could do. SKT would go on to win 3-1, becoming the first-ever team to win the tournament more than once.
