The Forbes YouTube rich list has been released, with an Irish YouTuber in the eighth spot. 

Seán McLoughlin, originally from Athlone and now living in Brighton, England, has been named as the most popular and successful Irish YouTuber, earning a reported $16 million in revenue from June 2017 to June 2018. Posting under the pseudonym Jacksepticeye, he uploads video game commentary videos once a day, a form of video called Let's Play

McLoughlin (28) clocks in at higher than such established YouTube celebrities as PewDiePie and Logan Paul, who earned $15.5 million and $14.5 million respectively. Meanwhile, Ryan ToysReview, a seven-year-old boy who reviews toys, earned €22 million during the same period, making him the most successful YouTuber. 

On his inclusion in the list, Forbes wrote, "Foulmouthed, energetic Seán McLoughlin is the most popular YouTuber in Ireland thanks to his colorful video-game commentary". 

"A few bad words haven’t kept him from going mainstream: He did a series for Disney and is developing exclusive content for live-streaming platform Twitch."

Renowned for his fast-talking commentary, enthusiastic gaming and coarse language, McLoughlin has long been Ireland's most popular YouTube account, despite only uploading videos since 2012. Speaking to The Independent last year about the swearing, he said "There's lots of swearing. The more you swear, the better. People react very positively to that apparently". 

McLoughlin joined YouTube in 2007 and started making his own videos in 2012. A mention by PewDiePie, another Let's Play YouTuber, caused his followers to soar. By February 2015, his channel had garnered one billion views and 3.2 million subscribers and today, many of his videos clock up over one million views individually. 

With 20 million subscribers already, his follower base grew massively through links with PewDiePie and entrepreneurial moves towards game and merchandise creation. He has hosted panels at various gaming expos and ran a successful tour through the UK and US.

Earlier this year it was announced that McLoughlin would produce original gaming content for Twitch, a streaming video platform, as part of a multi-year deal with Disney’s Digital Network. 

He also featured on last year's RTÉ 2 documentary Ireland's Rich List, which revealed he was worth €2.5m.

The main source of income for YouTube personalities is ad revenue, with many videos featuring a small advertisement that runs before the video plays, or during it. For comparison, Forbes wrote that when it comes to money generated by Ryan ToysReview, all but $1m of the $22m total is generated by advertising shown before videos, with the remainder coming from sponsored posts.
