Kittsbud started Supernatural.tv in September 2005 after the WB announced that Jensen Ackles would leave Smallville to star in a new horror/suspense television series. Kittsbud created the site for fans to discuss Supernatural as soon as the show started. The site quickly grew into one of the top fan sites for Supernatural with show-related news, spoilers, and images. In June 2008, Kittsbud turned over ownership of Supernatural.tv to BuddyTV. Abbey of BuddyTV was the webmaster. Supernatural.tv was open to contributions from fans, including episode reviews, fan creations, and reports from set visits and conventions. The site folded when Buddy TV did in 2018.
