History

KTBW originally signed on the air with the call sign KQFB on March 30, 1984. As KQFB, the station was originally locally owned by Family Broadcasting based in University Place, Washington. Family Broadcasting originally was going to broadcast Christian programming from several sources. Before the station went on the air, a minority interest in KQFB was acquired by the Trinity Broadcasting Network. When TBN acquired Family Broadcasting in full, the call letters were changed to KTBW on December 18, 1984.

TBN-owned full-power stations permanently ceased analog transmissions on April 16, 2009.[1]

KTBW-TV shut down its analog signal, over UHF channel 20, on that date.[2] The station's digital signal remained on its pre-transition UHF channel 14, using PSIP to display KTBW-TV's virtual channel as 20 on digital television receivers.

gollark: The current implementation is just """monte carlo tree search""" which plays 128 games entirely at random and sees how many it wins. I tried minimax/α-β pruning but those caused RAM implosions.
gollark: That would be effort, though.
gollark: Implementing a good "AI" opponent is proving surprisingly hard since I can't do tree-searchy things with any significant depth or the browser just runs out of memory.
gollark: My overengineered tic-tac-toe game advances inexorably.
gollark: Wow, it finished after just 160 seconds.
