Map: TV viewers still holding onto black and white sets There are 109 black and white TV licence holders in Omagh, or 5.5 for every thousand residents, the highest rate for any town in the UK. 13,202 households across the UK are holding on to their monochrome-only licences, compared to 202,000 in 2000. Over 25 million colour TV licences are in use today. Magherafelt, Dungannon, Enniskillen, Armargh and Newry have the next highest rates in the UK behind Omagh. The town with the most sets per person in England is Wembley, where there are 26 black and white TV licences, or three for every thousand residents. All of the black and white televisions currently in use require a set-top box since the analogue signal was switched off last year. Northern Ireland was the last country in the UK to switch off its analogue television signal in October 2012. Many viewers may be holding on to their monochrome sets to save money: a black and white television licence costs £49, nearly £100 cheaper than its £145.50 colour equivalent.
