K.M., thank you for clarifying the ownership of the short-lived KPOL-TV. Do you know why the original Channel 22 (KBIC) never went on the air?
I can speculate, based on Poole's other early ventures into television.
Poole put channel 53 on the air in Fresno as KBID-TV for five months in 1954 before taking it dark, saying that "the refusal of the networks to affiliate" was the reason (a common cause of failure in the early days of UHF). He also held a construction permit for channel 46 in Sacramento, which was to be KBIE-TV, but surrendered it in 1955.
Obviously the failure in Fresno was the reason he didn't try in the even smaller Sacramento market. But he likely thought there was potential in Los Angeles, if he could hold on long enough. So he kept channel 22 on the air (and technically, it was considered to be "operating") for nine years with nothing but the station ID slide airing (even operating at lower power in 1960-61 when he sold the transmitter's power amplifiers to KNBS-TV in Walla Walla, taking them back when that station failed in less than one year).
It is significant to note that even after Poole sold KBIC-TV and it officially began airing programming as KIIX, channel 22 went dark after one year and stayed dark for another year after that before becoming KPOL-TV, likely being supported by revenues from the radio stations. The only reason Murchison's partners bought the station was because they had the business news idea in mind, and had it not been for that the station probably would have gone dark again ... who knows for how long?
In 1970, they gave up operating in the evening, other than on weekends, and it wasn't until the beginning 1972 that they brokered out the Sunday evening hours to Korean and Japanese language programmers (and the rest of the week wasn't brokered out until mid-year, to Spanish language programmers). SelecTV didn't come along until mid-1978, so if they'd gone dark in 1966 it might have been a dozen years before it went back on the air.
