BTS, also known as the Bangtan Boys, is a South Korean boy band that has taken the world by storm with their catchy tunes and dynamic performances. Since their debut in 2013, BTS has garnered millions of fans across the globe and has become a global cultural phenomenon.

As with most successful acts, there is always the curiosity of when and how they started out, including when they signed their contract. BTS was formed by Big Hit Entertainment, a South Korean entertainment company, in 2010. However, it wasn`t until three years later that the septet, consisting of RM, Jin, Suga, J-Hope, Jimin, V, and Jungkook, made their official debut.

It was in 2012 that BTS began training under Big Hit Entertainment, and it was during this time that the members underwent extensive training in singing, dancing, and rapping. They also learned how to write their own music, which would eventually become a hallmark of their style.

In June 2013, BTS made their debut with the single „No More Dream,“ and it was the beginning of their incredible journey. Their debut album, „2 Cool 4 Skool,“ was released the same month, and it included tracks that showcased their skills and their unique style.

As for their contract, it was reported that BTS signed a seven-year contract with Big Hit Entertainment when they became trainees in 2012. This means that their contract was set to expire in 2019. However, in October 2018, it was announced that BTS had renewed their contract with the company for another seven years, ensuring that they would stay together until at least 2026.

In conclusion, BTS signed their contract with Big Hit Entertainment in 2012 when they began their training as trainees. The seven-year contract was renewed in 2018, which means the band members will be together until at least 2026. BTS has come a long way since they first started out, and their journey is far from over. Their music continues to inspire and unite fans worldwide, and they show no signs of slowing down anytime soon.
