I have a channel called HeroJournalism where I cover comics, video games, movies and cartoons, mainly genre stuff (superheroes, sci-fi, horror, etc...), and with a heavy focus on the history. I don't stream or do lets plays or walkthroughs, but I mainly do mini documentaries on the history, with original interviews and footage.
I've been at it for two years, and have 375 subscribers, but always looking to grow- if anyone here wants to subscribe, I'd be happy to subscribe to your channel as well. Just reply to let me know you did, or when you subscribe, drop a comment mentioning "Gamespot forums" and I'll automatically sub to your channel.
Here's a video I did on the Game Masters exhibit on video game history that was at my local science museum last year (yes, video games at the science museum!!).
