Offaly native Sean McLoughlin, better known as Jacksepticeye, made an appearance on Friday night's Late Late Show with Ryan Tubridy on RTE.
The 28-year-old spoke of having over 18 million YouTube subscribers and making a career out of his video game commentary episodes.
Jacksepticeye posts videos of himself playing and commentating on his favourite video games.
His energetic and brash style struck a chord with other gamers and he now enjoys a huge following across the globe.
His online name comes from a nickname made up for him by his schoolmates after he suffered an eye injury.

The Cloghan man started posting videos as a hobby around the time he studied tourism at AIT and moved to Athlone, but has now made his vlogging a full-time job. He has since moved to the UK.
Not only that, but he has amassed an estimated fortune of €2.5 million, landing him a spot on Ireland’s top 30 earners under 30.
