In the Los Angeles market, it was KRCA/62 Riverside (but transmitter on Mt. Wilson with the rest of the L.A. stations), now the flagship for Liberman's "Estrella TV" network. I seem to remember 62 running brokered Asian programming when it first signed on in the late 1980s but it was definitely "Spree" by the end of 1990, because it was on my cable system in the east San Fernando Valley then; Liberman has owned it since 1997 or 1998.
We also had HSN-owned KHSC/46 (the former religious broadcaster KBSA) at the same time running Home Shopping Club. It was sold to Univision in 2002 when they launched TeleFutura (now UniMás) as KFTL. When KBSA was still under construction in the 1960s it got its "fifteen minutes of fame" as Broadcasting misidentified it as being the future L.A. affiliate of what turned out to be the ill-fated Overmyer Network (the magazine had to issue an embarrassing correction the following week).
Both channels 46 and 62 were Home Shopping Network 24/7, with all the FCC-required news and public affairs programming coming in two- to three-minute capsules in what were supposed to be local commercial avails. I don't think E/I was required yet.
