Dan and Carrie are moving on to start their own new adventures, but we'll still keep making content at the same constantly improving-standard of quality we always have. There's too many of us working on the channel now for it to come to a halt. You'll still be hearing his timeless pitch-shifted voice in some of our videos over the next month.
Eventually we will have a new narrator for Extra History and all our other shows, Matt Krol, who comes from a TV and film production background. You'll get to "meet" Matt next week when we air his first Extra Credits episode! (No, we are not going to make him sound like pitch-shifted Dan. That is Dan's pride and joy alone.)
You can watch Dan and Carrie's goodbye in this posted video, starting around 7:34.
