There were some more or less popular reviewers/videomakers on the website "That Guy With The Glasses" (TGWTG). Years ago, before it simply became "Channel Awesome".
Reviewers like That Aussie Guy (Dan Rizzo), who got into such a HUGE falling-out with TGWTG that he was fired, his page on the Channel Awesome Wiki was deleted, and very little of his videos can be found. This was around 2007-2009. One of his shows was Riz's Rave Reviews, a video game review series.
A trailer video to his review, with a link still directing to the old thatguywiththeglasses adress.
And then there is Iron Liz, who was mostly known for being Linkara's girlfriend. She started a review series called Pen n Paper Corner, where she'd review tabletop RPGs. Those videos were hosted on Blip, and after it was shut down, she didn't bother to reupload/keep them, since she didn't think they were good.*
One episode managed to be mirrored:

I remember when I first found TGWTG/Channel Awesome, and there was a lot there then that isn't their now, considering it was at a time when there was an abundance of reviewers that were trying to be the next Doug Walker or James Rolfe. I remember watching the "Nostalgia Chick Winner" video, and one reviewer I never heard of called "That Chick with the Goggles" was present as well as Lindsay and Marzgurl, who I was more familiar with. Her time on the site was short lived, and it was obvious she left before I started frequenting the site around 2010-2011.
One should also discuss the reviewers on TGWTG's ill-fated and short-lived sister site Blistered Thumbs, which was where most of the game reviewers were, and was basically like a hybrid between TGWTG and ScrewAttack. Some reviewers like Angry Joe and Guru Larry are still around, but a lot of the Blistered Thumbs reviewers are pretty much forgotten now, especially since the site wasn't paid attention to that much in comparison to it's parent site.
