THEY may be reminiscent of a bygone era but whether due to nostalgia, austerity or just loyalty, there remains a contingent of Scots who refuse to replace their black-and-white televisions.
Official figures have revealed there are 710 black-and-white TV licences issued across Scotland, with Glasgow having the greatest share at 230.
Colour transmission began in 1966, yet the residual demand for black-and-white TV continues as a niche market.

There is also a financial benefit for TV owners, as the cost of a black-and-white licence has been frozen at £49 until 2016, whereas a colour licence is £145.50.
Jim McLauchlan, who carries out restorations at the Museum of Communication in Burntisland, Fife, said many viewers are simply content with their reliable black-and-white sets.
He said: "Aside from the cost of a licence, a reason to keep using a black-and-white TV could be to watch purely news broadcasts. Some may have a nostalgic attachment to black-and-white while others may not see the need for replacing their television."
