KLAC-TV's slogan is "Lucky Channel 13". There are different designs to the logo, but these weren't the official logo used for KLAC-TV.
KCOP (-TV)
1954–1956
KLAC-TV became KCOP, on channel 13. The logo shows the 1 with a badge and a police officer over the logo (only a hand and a police officer's head, playing on the COP part of the callsign) and a 3 next to the 1 with the words KCOP and "LOS ANGELES". This logo is still used on welcome mats until 1981.
During this logo's run, BHC Communications (including KCOP) would be acquired by News Corporation's Fox Television Stations division in 2001. This made KCOP a sister station to Fox O&O KTTV.
2002–2006
KCOP's last logo as a UPN affiliate. In 2004, it would be accompanied by the slogan "Get it On".
January–September 2006
Following the announcement of the shut down of UPN (whose programming would be merged with The WB to form The CW), all Fox-owned UPN stations, including KCOP, dropped the UPN name and logo from their on-air branding. KCOP reverted to their former "Channel 13" branding, and adopted an altered version of 2002-06 UPN era logo (note that the "13" square was changed after five years from a white background to a red logo despite keeping the same font). It still used the slogan "Get it On".
2006–2021
KCOP's logo when UPN and The WB merged to form The CW, and KCOP joined MyNetworkTV.
2006–2007
The short-lived 2nd logo from late 2006 to May 2007. This would also be used by XHDTV-TV until 2018.
2021–present
In July 2021, My 13 was officially changed to KCOP 13 dropping the MyNetworkTV branding.
