2013 over five dozen brands offered induction-cooking equipment, including both built-in and countertop residential equipment and commercial-grade equipment. Over two dozen brands offer built-in residential-use units; residential countertop units are offered by two-dozen-plus brands. The National Association of Home Builders in 2012 estimated that, in the United States, induction cooktops represented only 4% of sales, compared to gas and other electric cooktops. The global induction cooktops market was estimated at $9.16 billion in value during 2015. In April 2010, The New York Times reported that "In an independent survey [in 2009] by the market research company Mintel of 2,000 Internet users who own appliances, only 5 percent of respondents said they had an induction range or cooktop. Still, 22 percent of the people Mintel surveyed in connection to their study [in 2009] said their next range or cooktop would be induction."
