What is the most popular type of coffee maker

The most popular type of coffee maker in the world is the cold coffee maker.  Maybe because they are extremely simple to use and can make a pot of coffee fairly quickly. Hot water is run through the ground coffee which has been placed in a filter in the cup of the coffee maker. The hot water drips through the grounds and makes its way to the pot where it usually produces a fairly clear, decent tasting pot of coffee and doesn’t allow any coffee grounds to foul up the brew. Easy, convenient and still the most inexpensive coffee maker. I guest, because we are use to this coffee maker for century.
