KRET-TV, UHF analog channel 23, was an educational television station licensed to Richardson, Texas, United States, which was on the air from 1960 to 1970.
[1] The call letters "RET" stood for "Richardson Educational Television".
It was actually the first educational television station in the Dallas–Fort Worth area, signing on about six months before KERA-TV.
The frequency remained dark until 1985 when religious broadcaster KIAB-TV signed on the air.
The station was later sold to Univision and became KUVN-TV, the network's O&O for North Texas.
