were on the bottom right of the screen by the end of 2010. Commercial TV channels usually place their logos in the top left corner of the screen: among the larger channels Kanal D, Show TV, Fox and ATV use the top left, but Star TV uses the top right. A similar situation exists in Turkey's neighbour Greece, where most TV channels use the top left corner (including Star Channel, which is not related to its Turkish or Indian namesakes), with only Skai TV using the top right. The badges are either simplified or transparent during commercial breaks. Turkmenistan Turkmen TVs introduced DOGs in 1999. All of Turkmen DOGs are full-color, opaque & displayed on the bottom-left of the screen. Ukraine Ukrainian TV introduced DOGs in 1991 shortly after Dissolution of the Soviet Union. Ukrainian national broadcaster Pershyi introduced DOGs in 1991 as "УТ-1" (UT-1) in the bottom-right corner but changed to top-left corner of the screen from 1995 to 1998. Since 1998 most of Ukrainian TV channels place their DOGs in top-right corner of screen. United Kingdom DOGs most commonly appear in the top-left hand corner on British channels. DOGs were first used on satellite and cable television systems in their early days, when broadcasts were unmarked. Channel 5 was the first to use DOGs on an analogue terrestrial channel when it launched in 1997. The DOG was originally very bright and noticeable, and was soon toned down. Channel 5 said that the DOG was used to assist viewers in tuning to the new channel once its test transmissions had ceased. Following the rebrand to "five" in 2002 the DOG disappeared until late 2007. There have been two known predecessors to the digital on-screen graphic on British television, namely a small white outline rectangle that was broadcast on the screen throughout ITV's broadcast of the documentary Life by Misadventure: A Film about the Seriously Burned on 7 September 1973 to warn people that may be uncomfortable with its content, and similarly, Channel 4's infamous red triangle symbol, which was applied in the corner of the screen throughout a series of controversial late-night art films broadcast 1986–87, in addition to an ident before the films began, again in both cases to warn viewers of the content. The BBC initially introduced a DOG on each of its digital-only channels. In October 1998, it added DOGs to BBC One and BBC Two
