JacksGap has more than 4 million subscribers.It was originally created by Jack Harries. Finn Harries joined him afterwards, with the channel's subscriber doubling after that.
JacksGap was originally launched in July 2011 by Jack Harries during his gap year after he had left school. The main purpose of the channel was to document Jack's gap year. By September 2012 the site had 190,000 subscribers and the pay-per-click advertising revenue was enough to entirely finance the Harries' travels in Thailand. After Finn joined the channel, the views nearly doubled.
JacksGap attracts teenage girls in particular, with 88% of subscribers in this demographic.
As of March 2015, JacksGap has over 4 million subscribers.
In May 2014, JacksGap won two Screenchart! Channel Awards including; Best Directing for the Channel and Best Mini-Series or Short Film for their "The Rickshaw Run" videos! 
In January 2015, JacksGap posted a video called "Let's Talk About Mental Health" that was later referenced in an article on The Huffington Post in which he addresses the importance of starting an open conversation about mental health in order to reduce the stigma attached to it. 
In April 2015, JacksGap posted a video called "What Do You Believe In?" that announced Finn had moved to New York City earlier that year to study Design and Architecture for three and a half years, though he is still a part of JacksGap.
