<P> The origins of what is now known as the Kit Kat brand go back to 1911 , when Rowntree 's , a confectionery company based in York in the United Kingdom , trademarked the terms Kit Cat and Kit Kat . The names were not used immediately and Kit Kat first appeared in the 1920s , when Rowntree 's launched a brand of boxed chocolates entitled Kit Cat . This continued into the 1930s , when Rowntree 's shifted focus and production onto its Black Magic and Dairy Box brands . With the promotion of alternative products the Kit Cat brand decreased and was eventually discontinued . The original four - finger bar was developed after a worker at Rowntree 's York Factory put a suggestion in a recommendation box for a snack that `` a man could take to work in his pack '' . The bar launched on 29 August 1935 , under the title of Rowntree 's Chocolate Crisp ( priced at 2d ) , and was sold in London and throughout Southern England . </P>
