UhOhBro
Once dubbed "Greg/Onision's Failed Gaming Channel", UhOhBro is now Greg's most popular YouTube channel, being his only channel to surpass his main Onision Channel's subscriber count. It is his first channel to reach 2 million subscribers.
History
Greg created the UhOhBro channel on May 27, 2012 as a gaming channel. The channel was not well received by fans and did not gain very many subscribers or views.
By March 2013, Greg changed UhOhBro's format from a gaming channel to a reaction channel. (Source)
He says he did thing because his gaming videos were "not getting the views" and he didn't want to be fake. ($ource) The channel almost immediately began gaining a fan base and the subscriber count rose. (Source) On January 25, 2015, the UhOhBro channel reached 1 million subscribers. (Source) It was his second channel to reach that milestone. Eventually, UhOhBro surpassed Greg's main channel in subscribers and in January 2016 reached 2 million subscribers. (Source)
In 2016, Greg began incorporating gaming back into the channel by playing a game while reacting to images. When viewers began complaining about this new format, he says they were making themselves look dumb because "the foundation of UhOhBro is literally gaming." ($ource)
