A recent study in Britain found that coffee pod machines are showing a huge growth in sales, with 14% of Brits (almost 4 million households) owning a coffee pod machine. Sales of hot beverage machines grew by two-thirds over the last five years. Food preparation machines such as food processors, blenders and mixers have also shown a marked increase in sales over the last five years, up twenty-one percent for the same time period. Kettles, once a staple of the British kitchen, show a drop of two percent in sales over the same period. Kettles are traditionally used to boil water for tea, instant coffee and other hot beverages.
