Singapore Singapore has adopted the use of TV Ratings from 21 October 2011. They consist of PG and PG13 ratings for Free-to-Air TV and NC16 and M18 ratings in addition to the PG and PG13 ratings for Pay TV channels. For Free-to-Air TV, the shows rated PG may be aired anytime while PG13 should air between 10pm to 6am. For Pay TV, PG13 rated programmes can be shown anytime. Before the rated programme starts the TV channels will show a notification. From now on, only StarHub TV's and Singtel TV's self-packaged non-regional Pay TV channels ( e.g. StarHub TV's E City and Sensasi and Singtel TV's FashionTV HD and FashionTV HD on Demand, both of which features modeling nudity in certain programmes ) are enabled to carry NC16 and M18 rated content. FashionTV is also Singapore's first official M18 rated channel. M18 rated programmes can only be telecasted from 10pm onwards to 6am on Pay TV. Regional channels like Fox Life, Fox Movies and HBO Asia are unable to carry Media Development Authority's film ratings as they are targeted at the same region (a certain group of Asia territories), which results in programmes being subjected to external censorship of a much harsher nature outside Singapore territorial control. Only Video on Demand (VOD) Pay TV services are allowed to carry R21 content currently. G-rated programmes are not required to show a notification for any channel.
