Seven Network

1968–1970
This logo was used by Seven's Sydney station ATN-7 from 1968-70. This logo was from the 'Circle 7' design used by many ABC affiliates in the U.S. It was around this time that the network became known colloquially as the "Seven Network".

1970–1975
The first logo used across the network consisted of the number 7 inside a ring.

1975 (only Melbourne)
This was used only on Seven's Melbourne station HSV-7 for its first colour programmes in March 1975 until September 1975 when it adopted the 'Rainbow 7' logo.

1975–1989
On 1 March 1975, colour television was introduced across the network (in 8 years of distance from Network Ten's color programming launch), along with a new logo which incorporated a bright ring of the colours of the visual spectrum.

1989-2010
In 1989, the network attempted to revert to its original name through a complete rebrand; however, the Seven Network name was ultimately kept and became the official name of the network until 2010.

1989–1999
Along with the recently renamed Seven Network came a new logo with the circle modified to incorporate the 7. American television station WJLA-TV used a logo similar to this logo (with several variations) from 1975 to 2001.

2000–2003
In January 2000, Seven did away with the circle logo and launched their new ribbon logo which in effect was two angled trapezoids.

2003–present
In September 1, 2003, the ribbon logo was simplified and became solid red. As a secondary logo in January 2000, the September 1, 2003 logo was appeared on-screen, but instead of solid red, it was solid white.
