'Superstar K' is not airing next year as well.
Mnet told StarToday, "There's nothing planned for a new season of 'Superstar K' in 2018 as well."
'Superstar K' started in 2009, and is one of Korea's first audition shows. It's the birthplace of stars such as Seo In Guk, Huh Gak, John Park, Jung Joon Young, Roy Kim, and more. However, lately the show has been suffering in both ratings and attention.
The show did not air in 2017, but Mnet had denied it was coming to an end.
