The town of Whitehaven in Cumbria has become the first place in the UK to undergo the official switchover from analogue to digital TV.
BBC Two was the first to go digital at 0200 BST on Wednesday, with the remaining analogue channels to be switched off on 14 November.
Around 25,000 households will need Freeview, satellite, cable or broadband in order to watch television.
Analogue TV will be switched off in the rest of the UK by the end of 2012.
About 84% of British households have already installed digital equipment, according to media watchdog Ofcom.
