I don't know about Channel 13 (but I would assume it stayed educational programming, as my local January, 1964 TV Guide backs that up...no news presence, just a lot of Spanish III-B and Biology! And off the air by 10PM weeknights) but Channel 11 did have a news presence then, which lasted up to the early 1980s, then returned in 1990. I don't have my tapes handy that Sanda McQueery-Bloxom made on 11/22 and 11/23/63 (Sanda was home taping newsman/husband Russ Bloxom on KXOL-1360 that day, and switched the mic over to the TV for coverage when KXOL was in a lull) but, since Sanda worked for KTVT at the time, I believe there were some short recordings made of what KTVT was doing, which would have been news. On Fridays (like 11/22/63 was, and this was probably the normal weekday routine,) KTVT was doing 5 min newscasts at 10AM and 2:55PM, 15 mins at 5:45PM and 10PM, and a 20 min newscast at noon. A short newscast came on at the very end of the broadcast day, starting at 1AM. George Nolan and the late Bob Hazlett handled anchor duties. KTVT still had KFJZ-AM/FM in the old West Fwy building with them then (albeit under different owners by then,) so I'm sure they shared news resources that day and weekend.
I'll check out the other thread. Feel free to copy and paste this if it would help!
