The first 14 episodes were recorded and produced in 2007 and posted on Doug Walker's YouTube page. When the videos were removed for legal reasons in 2008, Walker brought them to his own channel on ThatGuyWithTheGlasses.com, where he continued producing new Nostalgia Critic reviews on a weekly basis, and the rest is history.
I'm the Nostalgia Critic. I remember it so *you* don't have to.
Starting with the Battlefield Earth review, the worst line from the movie/movies reviewed is repeated over the Channel Awesome logo.
