Although part of PBS, PBS Kids was a separate tv network, founded in 1999, and was targeted to children aged 2-7 years. The PBS Kids Channel ran for six years and was largely funded by DirecTV. The channel ceased broadcast on Sept. 26, 2005, in favor of a new commercial joint venture, PBS Kids Sprout, which is a partnership owned by Comcast. About half of PBS TV stations still program a children's channel themselves over their multicasting service , such as KETC, WNET, WHRO, UNC-TV, Georgia Public Broadcasting, Wisconsin Public Television, WGBH, KQED, and WGBH. On PBS, two blocks of programming are currently included in PBS Kids, including PBS Kids Go! and the PBS Kids preschool block, and the former block, PBS Kids Bookworm Bunch, which was launched in 2000 and cancelled in 2004.
