More than 70 years of analogue broadcasting in the UK has come to an end with the complete switchover to digital television.
Anyone still using the original signal lost access to channels at 11.30pm on Tuesday night.
The final broadcast was transmitted in Northern Ireland, simultaneously by the BBC and UTV, and fronted by Eamonn Holmes.
It reviewed an era which included the Second World War, the Cuban Missile Crisis and the end of the Soviet Union.
Dame Mary Peters from Belfast, the 1972 Olympic gold medallist in pentathlon, turned the final analogue switch off at a transmitter in the city.
BBC Ceefax, the world's first teletext service, also made its final bow.
- The UK's conversion to digital TV began in 2007, with a region-by-region switch off
- The analogue channels have been replaced by over 70 digital channels
- It means there is new capacity for mobile broadband services, 4G
