KGO-TV

==1949–1950==
KGO-TV first signed on the air on May 5, 1949, as the San Francisco Bay Area's second-oldest television station, signing on five months after KPIX (channel 5). It was the fourth of ABC's five original owned-and-operated stations to sign-on, after WABC-TV in New York City, WLS-TV in Chicago and WXYZ-TV in Detroit, and before KABC-TV in Los Angeles, all broadcasting on Channel 7. In addition, it is the only ABC station to keep its original call letters, which were inherited from KGO radio (810 AM). 
Until 1995, KGO-TV was the only network-owned television station in the Bay Area, even throughout the time when ABC underwent ownership changes: Capital Cities Communications bought out ABC and merged with the network in 1985, the combined company Capital Cities/ABC was then sold to The Walt Disney Company in 1996.

===1962–1996===
In 1962, ABC commissioned designer G. Dean Smith to create a proprietary logo for its owned-and-operated stations, known as the "Circle 7". This logo has since expanded into use by many ABC stations not owned by the network. KGO-TV was the first station to use this logo. It predates Paul Rand's ABC logo by 4 months.
===1996–2003===
Logo shared with sister stations WLS-TV and WABC-TV.
===2003–present===
This logo's design is shared with sister station KABC-TV in Los Angeles.

====2021–2024 (secondary); 2024–present (primary)====
The current version of the logo was introduced in 2021 as a secondary logo for network promos before coming into primary usage in February 2024.
