Almost a quarter of US households plan to buy one.
The Consumer Electronics Association (CEA) claims 22 per cent of American homes will buy smartphones in the next year, which makes the device the most popular consumer electronic.
The next most popular items are HDTVs and digital cameras with 17 per cent and 15 per cent, respectively.
Additionally, tablets will experience its highest sales increase to date, as 14 per cent of homes buy one alongside notebooks and laptops.
Chris Ely, CEA’s manager of industry analysis, said: "Consistent with past research and trends we are seeing, tablets and smartphones will continue their dominance in the marketplace over the coming year.
"As consumers continue to integrate these mobile connected devices into their everyday lifestyles, we expect to see an increase in ownership of all-in-one devices and related content."
