Digital on-screen graphics in the Nuclear Islands

A digital-onscreen graphic is a logo or rating that appears on a TV screen.

Heartlake
This does not include the regions of Inner Paris, Inner Dublin and Zachimainei.

It is legally required for all terrestrial Heartlakian channels to have a DOG. HLN-TV started using its DOG in 1999, with Channel 2 following in 2000 and ITV in 2002. The regional FourTV channel's DOG policy depended on the channel controller for that region. The Fifth originally launched without a DOG, but when a law was made that all terrestrial channels must carry DOGs in 2006, a DOG was added to The Fifth and FourTV had to carry a DOG in all regions. Disney Channel was the first channel to not remove its DOG during commercials. When TuTu replaced ITV in 2015, it was the first channel to have a fully-coloured permanent DOG.

Island of Sally
SBC launched in 1998 with a DOG. In 2004, the DOG was toned down. Channel 4's DOG was introduced in 2003, a year after launch in 2002. All DOGs on Sallyish channels must be 4:3 safe.
