From DCRTV: The Retro TV Network (RTN) has apparently gone belly-up due to lack of advertising revenue. We’re a little confused though because a check of the channel (A.K.A. “11.3”) over the weekend still seemed to show classic programming from between the 1950s and 80s. If this is true, then it’s a double whammy for WPXI and their digital subchannels. NBC discontinued its “Weather Plus” which aired on 11.2 up until the beginning of December 2008. Nothing has replaced it yet.
