Seven Network

1968–1970
This logo was first used by Seven's Sydney station ATN-7 from 1968-70. This logo is 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".

1956-1970
HSV 7 was Australia's first Melbourne station that began transmission on 4 November 1956, one day before its Sydney station ABN 2.

1975
This logo was used for its first colour programmes between March and September 1975 when it adopted the 'Rainbow 7' logo.

1959-1966
Transmission began by the start of November 1959, one day before ABQ 2, the other station which is owned by the ABC.

1959-1967
SAS 7 began transmission in Adelaide on 24 October 1959 as ADS 7.

1959-1975
TVW 7 was Australia's first Perth station to begin transmission on 16 October 1959, prior to both Brisbane and Adelaide stations, BTQ 7 and ADS 7 (now SAS 7).

1975–1977


This was used only on Seven's Perth station TVW-7 from March 1975 to 1977 when it adoped the rainbow logo used by the eastern states.

1970–1976
As part of the renaming into Network 7, in 1970 this logo was used across the network with a modern 7 inside a ring.

BTQ in Brisbane would continue to use this logo until 1976.

1975–1989


Colour television was introduced across the network on 1 March 1975, along with a new logo incorporating a bright ring of the colours of the visual light spectrum.

This logo was also used for its Brisbane station BTQ 7 between 1976 and 1989, as well as its Perth station TVW 7 between 1977 and 1989.

1989–1991
In 1987, 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. The name appeared at the end of programmes from 1987 till 1991.

1989–1999
On 23 January, 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 between 1975 and 2001.

2000–2003
On 1 January 2000, Seven did away with the circle logo and launched their new ribbon logo which in effect was two angled trapezoids. Used in five colour variants: red, orange, yellow, green and blue, to symbolise passion, involving, fun, life and energy respectively.

2003–present
The logo was simplified on 14 September 2003, effectively becoming simply two angled trapezoids, losing its gradient, shadows and colour-coded usages to become solid red.
