Zeitgeist TV is my JustinTV channel that I use for playing documentaries pertinent to the Zeitgeist movement. If you want to participate in the chat room you will have to make a free JustinTV account. If you do this, just like with blogtalkradio.com it will notify you via email whenever I am going on live on Zeitgeist TV when you favorite the channel. Zeitgeist TV has been a great tool for attracting new people to the movement!
