GAMST's history began on AfreecaTV on February 17, 2012. He quit broadcasting on November 30, 2013, to become a comedian, but after failing, he returned. He took his first steps toward his prime in 2018 and became famous. In 2019, he hit rock bottom and went into self-reflection. After two months, he returned and rose again through League of Legends. In 2020, he expanded his gaming scope and focused on football. He took another break in 2020. In 2021, he participated in tournaments and even shaved his head. After a hiatus, he returned in late 2021. In 2022, he returned from another break, went on a diet, caught COVID-19, and did live commentary for the Qatar World Cup. He currently does football commentary and YouTube simultaneously. He founded Gam Company. His broadcasting style involves pre-planned content or ad-libbed roleplays. He is a good actor. He is skilled at football games and commentary, the latter being his most iconic and popular content. He is funny, outspoken, and a good host, though he lacks preparation. He eats well and works his managers hard. He is a mood maker and good at recruiting other broadcasters. Surprisingly, he is quite a coward. Teasing him for his outbursts has become a culture in his stream. He has weak mental fortitude, and his broadcast quality varies with his condition. He has a lot of trivia knowledge, but his gameplay style is polarizing. He is overly emotional and gets excited easily. He reacts sharply to supporting roles and his energy dies down if the reaction is poor. He is quite self-conscious. His catchphrase 'Jjase!' is a celebration. The 'Control Tower' is a dance emphasizing his jaw with a solemn expression. The 'GAMST Tackle' became a meme after he tackled so much in futsal that players couldn't throw the ball. 'Ss-eop-sae' is short for a rude baby. 'Run~!!!' is a catchphrase used when he fails at microtransactions or upgrades on a FIFA account. 'Sleu... sleu' means stop. 'Moe!' means 'What are you doing?'. 'Is this Bi-Gam?' is short for BJ GAMST and is used for him as a mood maker. 'Taeng-gu' is used when calling someone. 'What is this!!!' became a meme when he hit his chair in anger after Korea lost in the 2026 North & Central American World Cup.
