ITV plc

1955–1989
No official logo existed prior to 1989, when ITV Network was set up. Sometimes, network trailers would use a logo, but these changed from season to season. It wasn't until 1989 that the regional franchisees formed a network centre and created a unified brand.

(2005)2006–present
Note: ITV4 used this logo from launch in 2006, but the other ITV channels didn't adopt it until January 2006, when it became the official corporate logo.
