chocolate bar made by food company nestle.this bar was initially launched in london in September 1935 as 'Rowntree's Chocolate Crisp'. It became 'KitKat' in 1937.

No one can be absolutely sure where the name 'KITKAT' came from but it is believed to be from the famous 1920's KITKAT Club in South East London which had some influence. As the building had very low ceilings, it could only accommodate paintings which were wide and not very high. In the art world, these paintings were known as 'kats'. It's believed that KITKAT derived its name from paintings, which had to be snapped off - just like the chocolate bars - to fit into the rooms with the low ceilings.
