1. KitKat is a popular chocolate-covered wafer bar that was first introduced in 1935 by Rowntree's of York, a British confectionery company.

The original KitKat was called "Rowntree's Chocolate Crisp," but it was later renamed to KitKat after the company merged with Nestle.

The chocolate bar consists of four crisp wafer fingers covered in smooth milk chocolate.

KitKat is known for its iconic packaging, which features a red wrapper with the brand name and logo on it.

The slogan "Have a break, have a KitKat" was first introduced in 1957 and has become one of the most recognizable advertising campaigns in the world.

KitKat is now available in over 80 countries and is one of the best-selling chocolate bars in the world.
