A small group of players that represented the SoloMid.net community would become the original TSM team: Brandon "Saintvicious" DiMarco, Shan "Chaox" Huang, Brian "TheOddOne" Wyllie, Choi "Locodoco" Yoon-seop, and Reginald.

By then, both SaintVicious and Locodoco had left the team, and Christian "TheRainMan" Kahmann and Alex "Xpecial" Chu had replaced them to complete TSM's roster of the first season.

Following a successful performance in the group stage, they faced a setback in the upper bracket semifinals, when they were defeated by Against All Authority [fr] (aAa) by a score of 1–2.

They took part in the Global Challenge Cologne, the first live event of Intel Extreme Masters Season VI, as well as ESL Major Series VIII.

[10] Following a disappointing performance at the 2012 IEM World Championship in Hanover, TSM announced that TheRainMan was departing from the team due to internal issues.

In August, at the MLG Summer Arena, TSM defeated Curse Gaming by a score of 3–0 and only lost to Azubu Blaze, who ultimately claimed the title and were widely regarded as the world's top team at that time.

In a random draw conducted by Riot, Azubu Frost, the top seed from Korea, was selected to enter the event in the group stage.

[14][15] Following a match in which WildTurtle achieved a pentakill, he assumed the starting position for TSM, and the team finished the spring split regular season in first place.

As the playoffs arrived, the newly configured TSM, with WildTurtle in the lineup, navigated through the semifinals to face the finalist, the sixth-seeded Good Game University (GGU).

However, the championship match was a one-sided affair, as Cloud9, a team that had only dropped three maps throughout the entire season, outclassed TSM in every aspect of the game and claimed the title from the defending champions.

[14] At the Season 3 World Championship in October 2013, TSM found themselves placed in a group stage alongside GamingGear.eu from the Commonwealth of Independent States (CIS), Lemondogs from Europe, SK Telecom T1 from South Korea, and Oh My God from China.

[19][20] In the 2014 NA LCS spring split, Reginald chose to retire from professional play, shifting his focus to team management, and was replaced by Bjergsen.

They replaced OddOne with German import Maurice "Amazing" Stückenschneider and adjusted their bottom lane by signing rookie Nicolas "Gleebglarbu" Haddad in place of Xpecial.

[22] Although TSM remained competitive with Cloud9 for a significant portion of the spring split, their dramatically altered starting lineup caused them to slip back into the middle of the pack, finishing third in the standings behind both Cloud9 and the all-Chinese club, LMQ.

[14] During the 2014 League of Legends World Championship in September 2014, Team SoloMid was placed in a group alongside Starhorn Royal Club from China, SK Gaming from Europe, and Taipei Assassins from Taiwan.

[26] In the midst of the 2015 NA LCS spring split, in March 2015, Team SoloMid participated in the 2015 IEM World Championship held in Katowice.

[34] In November 2015, the team picked up top laner Kevin "Hauntzer" Yarnell, jungler Dennis "Svenskeren" Jognsen, and support Raymond "KaSing" Tsang.

[43] In November 2016, Doublelift announced that he would be taking the spring split off in order to "recover mentally and refuel," and the team signed their former AD carry WildTurtle as his replacement.

Despite losing the first two games of the match, TSM managed to reverse sweep their opponents, ultimately winning 3–2 and securing a place in the main event group stage in Rio de Janeiro.

[53] In the playoffs, TSM won against Team Dignitas in the semifinals to advance to their tenth consecutive NA LCS Finals, where they faced Immortals.

[55] TSM qualified for the 2017 League of Legends World Championship and was drawn into a group along with China's Team WE, Europe's Misfits Gaming, and Taiwan's Flash Wolves.

The team parted ways with Svenskeren, Doublelift, and Biofrost and brought in Michael "MikeYeung" Yueng, Jesper "Zven" Svenningsen, and Alfonso "Mithy" Aguirre Rodriguez as their replacements.

[70] Before the start of the 2019 LCS spring split, Grig was benched due to a wrist injury, and TSM promoted Matthew "Akaadian" Higginbotham from their academy team as his replacement.

The roster faced significant challenges in the jungle position, with three different junglers, including Mingyi "Spica" Lu, starting matches within an eight-week span, replacing both Grig and Akaadian at various points.

Additionally, they made a trade with Counter Logic Gaming, sending Smoothie to CLG in exchange for Biofrost, who returned to TSM as their support player.

The team subsequently signed AD carry Edward "Tactical" Ra, mid laner Zhu "Keaiduo" Xiong, support Wei "Shenyi" Zi-Jie, and head coach Wong "Chawy" Xing Le.

[109] In July, during the middle of the split, Huni stepped down from the starting roster due to a wrist injury and transitioned to a coaching position a week later.

[113] For the 2023 LCS spring split, the organization decided to part ways with Instinct and Spica while signing jungler Lee "Bugi" Seong-yeop and AD carry Toàn "Neo" Trần.

[116] In between splits, TSM parted ways with Solo and Maple, signing mid laners Lee "Ruby" Sol-min and David "Insanity" Challe.

As part of the sponsorship, TSM Snapdragon participated in a weekly web series called "Gamecrib," which premiered on February 20 and ran until June 14, 2013.
