Today is a very special day in internet horror history
On June 10th, 2010 the famous Slenderman character was created and coined by Eric Kundson (also known by his alias Victor Surge on the SomethingAwful fourms), which inspired content creator Troy Wagner to put the character into a visual platform
In the course of 10 days, him and his friend at the time and co-writer Jospeh DeLage created what is now the father of Alternate Reality Games (the ARG), Marble Hornets, which is a display of public voyeurism to tragedy, mental illness and an unreliable narrative to an interactive audience. Now it has created a film (which, to be fair, wasn't good but still an achievement considering it started off as a YouTube series) and now is being brought into the comic scene, illustrated by Jackie Reynolds.
This inspired several other slenderverse serieses to come into pursuit (Such as Everymanhybrid and TribeTwelve, which expanded on the concept of the core themes Marble Hornets created in both narrative and interaction), and even today we can credit things such as Petscop and even television adult swim shows like This House Has People In It
Truly this series has shaped how we see the horror scene, and utilized it's online platform to the fullest. It has created a subgenere of horror that many people have enjoyed creating and watching. Marble Hornets was the creation of something much bigger than expected.
And even though I, myself, was not there to witness the first upload release (being of age six), I have been impacted dramatically by its creation and it has left a profound impact on many others.
Happy birthday, MH!
