Relativity Demand on Amazon.com

I just randomly did an Amazon.com search for 'Relativity' in the DVD category and it actually lists the show (it never had previously) as being unreleased until like, 1969. I was wondering if this one of those things Amazon does to gauge interest in a product in order to tell the owner to release it (I know they did this with 'thirty-something' and 'Lois and Clark'). It was one of those dealy-things where you add your e-mail to be notified when it will be released. Anyways, everyone go add your e-mail!
