Seventeen (Hangul: 세븐틴), also stylized as SEVENTEEN or SVT, is a South Korean boy group formed by Pledis Entertainment in 2015. The group consists of thirteen members divided into three sub-units, each with a different area of specialization: a ‘Hip-Hop Unit’, ‘Vocal Unit’, and ‘Performance Unit’. Seventeen has released two studio albums and five extended plays.

Seventeen has earned a reputation as a “self-producing” idol group, with the members being actively involved in the songwriting and other aspects of the group.

Starting in 2013, Seventeen appeared in regular live broadcasts of a show called Seventeen TV on the online streaming platform UStream. The show had multiple seasons in which the trainees were introduced and shown practicing performances, with some seasons ending in Like Seventeen concerts.

Prior to debut, Seventeen also appeared in the reality TV show Seventeen Project: Big Debut Plan, broadcast on MBC between May 2–26, 2015. The show concluded with the group’s debut showcase.

Seventeen debuted on May 26 with a live showcase televised by MBC. They were the first male K-pop group to debut with a one-hour live showcase on a major broadcasting channel, with label-mates Lizzy and Raina serving as MCs. Three days later, their first EP 17 Carat was digitally released. 17 Carat became the longest-charting K-pop album of the year in the US and was the only rookie album to appear on Billboard’s “10 Best K-pop Albums of 2015” chart.

On September 10 their second EP Boys Be was released, which would later become the highest selling rookie album of 2015. The album’s success earned the group awards at the Golden Disk Awards, Seoul Music Awards and Gaon Chart K-Pop Awards. Seventeen was also the only K-pop group on Billboard’s “21 Under 21 2015: Music’s Hottest Young Stars” list.

Seventeen held a four-date concert series titled 2015 Like Seventeen – Boys Wish from the 24th to the 26th of December as an end-of-year celebration in Seoul. After the concerts’ success, Seventeen held two related concerts the following February in 2016, entitled Like Seventeen – Boys Wish Encore Concert.

Seventeen’s first full-length studio album Love & Letter was released on April 25, 2016. The album charted on the Oricon Weekly Pop Album Charts in Japan besides success on domestic charts. Seventeen received their first win on a music show with the album’s lead single “Pretty U”.

Love & Letter was later re-released as a repackaged version on July 4 along with the lead single “Very Nice”. Promotions were immediately followed by Seventeen’s 1st Asia Tour 2016 Shining Diamonds, which included venues in South Korea, Japan, Singapore, Australia and China.

On December 5 the group released their third EP Going Seventeen, which outsold Love & Letter.

Seventeen held six concerts in Japan between February 15–24 named 17 Japan Concert: Say The Name #Seventeen. The concerts attracted a total of 50,000 spectators despite the group’s not having officially debuted in Japan. On April 1, Seventeen became the first idol group to have a second season of the show One Fine Day after filming the series during their stay in Japan. The second season was titled One Fine Day in Japan and was created in collaboration between South Korean broadcaster MBC and Japanese network Music On! TV.

Seventeen’s fourth EP, Al1, was released on May 22, 2017. A series of videos titled 2017 Seventeen Project and three music videos subtitled Chapter 0.5 Before AL1 were subsequently uploaded.

The group completed their first world tour, 2017 Seventeen 1st World Tour “Diamond Edge”, during which they visited thirteen cities in Asia and North America, on October 6.

On November 6, the group’s second full-length studio album Teen, Age was released.

Seventeen released a special album on February 5, named Director’s Cut. Although Director’s Cut contained all tracks from the previous Teen, Age album, it was promoted as a special album instead of a repackaged one due to the presence of four new tracks, including lead single “Thanks”. “Thanks” reached first place on iTunes charts in 29 countries, including countries from North America, South America, Europe, and Asia. Time magazine named Seventeen one of the best K-pop groups during this promotion period.

Seventeen officially debuted in Japan on May 30 with their first Japanese mini-album, We Make You. The music video for the lead single “Call, Call, Call!” was released on May 16.

Seventeen released their fifth EP, You Make My Day, on July 16. You Make My Day broke the group’s personal record for most sales in the first week after release, and was awarded with Platinum status. Promotions for this album took place in between the Ideal Cut concerts in Seoul and concerts scheduled in other countries in Asia.

Seventeen released their sixth EP You Made My Dawn on January 21. The title track ‘Home’ is considered their most popular release yet, winning ten trophies on weekly music shows. The EP also attained two triple crowns which consist of three consecutive wins on any one weekly music show, and a grand slam which consists of winning trophies on Music Bank, Inkigayo, M Countdown, Show! Music Core and Show Champion in a single promotion period. It is the group’s best-sold release to date.

On March 21, 2018, members Hoshi, DK and Seungkwan debuted as a subgroup called BSS or BooSeokSoon, a common nickname for the three members together. The group released their debut single “Just Do It” and enjoyed a short promotion period.

Seventeen earned three rookie awards in their debut year, and have since earned four bonsangs, or main prizes. They have also gained several awards for choreography and dance performance.
