In the UK every TV must be covered with a TV license by the government to allow someone to watch or record content and to watch BBC on iPlayer or any device. Thus, the government is able to tell how many people have TVs and how many TVs of each kind of still around.
Weirdly, this revealed that despite half of the UK’s TVs having internet connectivity, 7161 people still use a black and white TV. This is mostly condensed in London with 1,768 monochrome TVs, followed by the Midlands with 431 and Greater Manchester with 390.
However, since 1967, when the first regular colour broadcasts started taking place the amount of black and white TV licenses has steadily decreased from around 212,000 in 2000 to less than 10,000 in 2015.
