What are (were) some TV stations that only existed for a short time? I'm talking maybe one to three years at most, and did not return to the air in any way, shape, or form (such as under different owners, call letters, etc.). And I'm only counting actual licenses, not applications or construction permits. And yes, LPs, CAs, and translators also count, but again, only actual licenses.
As I mentioned in another thread, KKOG channel 16 in Ventura, CA, lasted only nine months. That's the only one in my market that never returned to the air at all. As stated in that same thread, the frequency corresponding to UHF channel 16 is now used for mobile radio in Los Angeles.
How about other posters? What stations win the prize for shortest existence in your respective markets? Discuss! In York, Pennsylvania there was WNOW TV (channel 49) that only lasted a year or so in the early 50s. It was a Dumont station that went under right after the network did. There tower was later used for an fm radio station (105.7) and still stands to this day.
