Origin of the Name

In Ireland, "Jack" is a common nickname for the name "Sean", and both his mother and friends called him this. His friends started calling him "Jacksepticeye" after a football accident where he got an eye laceration from a friend's glasses. According to him, the wound bled for quite some time and became infected after a few weeks, hence the name "Jacksepticeye". (Septic is a medical term referring to a systemic infection).

Channel history

Jack created his YouTube channel on February 24th 2007. Jack was a fanboy of Markiplier and PewDiePie and watched their content, becoming his inspiration to start YouTube. He didn't start making his own videos until November 2012, his very first upload being a Metal Gear Solid 4 impression on Solid Snake. According to Jack in a 2017 video, he explained he originally wanted the channel to be dedicated to impressions.

After hearing that making your own content on YouTube was a "job", he did just that, although he was pressed for time to make videos since he was also studying for exams in college. Mark noticed Jack by writing on Twitter that he had entertaining videos and Pewds gave him a shout out in a competition. After graduating from college in 2014 and earning a degree in Hotel Management, he has since focused on his YouTube channel.

Jack mainly focuses on gameplays on a variety of different games, from indie to horror to upcoming releases, and occasionally vlogs. He is known for his loud, bouncy but caring personality and constant positivity, but tones down to seriousness on some occasions when something crops up. He shows his appreciation for his fanbase multiple times, such as making a subscriber milestone video and more recently SepticArt, admiring fans creativity on their works.


As Jack got more well known worldwide for his videos, he earned various opportunities worldwide, such as attending Indy Pop Con for the first time in 2015, Insomnia 62 in Birmingham, UK in December 2015 and PAX East and PAX West every year in America. In March 2017, he co-hosted the D23 gaming event in California alongside YouTuber Strawburry17. In late September 2017, Jack began his very first tour "How Did We Get Here?" and in October 2017, he toured Europe with the Game Grumps for "Ready Player Three."

More recently, he was interviewed on the Late Late Show in Ireland on February 23rd 2018 and met some fans there.
