I’ve been wondering about the extremely obscure PBS station, KWSU in Pullman. I have not seen any schedule listings for it, and it always seemed to be very different from other PBS stations. But I got thinking about it because a relative recently sent me some Sesame Street episodes taped from that station. It seemed to be called “Northwest Public Broadcasting.” But whenever I looked at the listings for KWSU, it didn’t seem to have Sesame Street or any of the popular PBS kids shows. Does anyone know anything about the history of KWSU or listings for it?
