KTVU

1975–1997


Since its first use in 1975, this logo has been affectionately known as "Circle Laser 2"; the nickname is derived from the "Laser II" spaceship featured on Captain Satellite, KTVU's afternoon children's program that ran in the 1960s.

1997–2015


After Fox tightened branding standardizations for its affiliates, KTVU obliged by adopting the "Fox 2" branding and adding the Fox moniker to the "Circle Laser 2" logo. The "Fox 2" brand was used obliquely in promotions for KTVU's news programming, with the station employing KTVU Channel 2 News or similar variations.

2015–present
After is 2014 acquisition by Fox Television Stations, the Fox portion of KTVU's branding gained more prominence by the start of 2015, with the network logo appearing side-by-side with KTVU's longtime "Circle Laser 2."
