British social media personality and Britain's Got Talent judge Olajide Olatunji, widely known as KSI, has announced his departure from the YouTube collective Sidemen after 13 years. The group, which he co-founded in 2013 and has amassed 23 million subscribers, is known for its football, comedy, and challenge videos. KSI stated that this was the hardest video he has ever made, and the decision to leave was personal, stemming from feeling pulled in multiple directions and unable to commit 100% to the group. His spokesperson confirmed the exit to the BBC, and while the Sidemen expressed surprise, they wished him well. KSI's final Sidemen video was released on May 31, marking the end of his significant involvement with the collective, which boasts over 140 million combined subscribers across its members.
