Congrats bro. How long has it taken you?
Channel started July 1, 2006.
Up until November 2013, I only used it for hosting several bragging videos about how I beat the toughest enemies in Final Fantasy 7 and 8 and the Kingdom Hearts games, funny Star Trek clips I found, and other random things that I wanted to be able to link people to.
From November 2013 to March 2015 I used it for hosting videos demonstrating progress I was making on mods I was creating for the 1997 RTS game Total Annihilation.
In October 2014, I discovered PewDiePie and other Let's Players for the first time and decided to get in on the action. I LPed 2 older games, then did half of another when I decided it wasn't what I wanted to do.
Also at this time I found the "X in G-Major" meme and modified it into what I call "Horror Version". I made several of these and didn't intend to do very many more.
During all that time, my subscribers bounced back and forth between 0 and under 100. I never paid attention to it.
On January 29, 2015 I uploaded my Frozen - Let It Go one and by March 31st it had 54k views. I had around 100 subs. It then got suggested on a Let It Go video by a really popular channel and I had 1,000 subscribers on April 18.
Since then, I averaged 600 subs a month for the rest of 2015, double that per month in 2016, and this year's monthly rate is looking about double that. During 2015 I changed the theme of my channel to be just the Horror Version one and almost all my videos are requests from viewers. Halfway through 2016 I started uploading daily.
