STV is a free-to-air public broadcast television channel owned and operated by the STV Group. It is made up of the Central Scotland and Northern Scotland ITV public broadcaster licences, formerly known as Scottish Television (now legally STV Central Ltd) and Grampian Television (now legally STV North Ltd) respectively.
The STV brand refers to the on-air name used by Scottish Television for much of its history - notably in the 1970s and early 1980s. This brand remained in conversational use amongst the local public afterwards.
