Digital point-and-shoot cameras have also seen their best days. The proportion of households with a digital camera, a product slowly cannibalised in the smartphone revolution, peaked in 2009 at 60 per cent. It has since dropped to 50 per cent.
"Remember how amazing they were? You could take a photo, see it straight away, and then save through a cord to your computer's hard drive, and email through Hotmail as an attachment to your family and friends," said Mr Martin.
"Between 2000 and 2009, almost 5 million households purchased a digital camera. By then, though, you could take photos on your phone and instantly share it on social media. So half a million homes chucked their digital cameras away."
