KitKat

Kit Kat is a chocolate-covered wafer bar produced by Nestlé in most markets. The standard format consists of four thin rectangular wafer fingers, coated in milk chocolate and packaged as a single bar. Each finger is designed to be broken away from the rest, a feature highlighted by the advertising slogan Have a break, have a Kit Kat.

Kit Kat was introduced in 1935 by Rowntree's of York, United Kingdom. The origin of the name is not definitively known; one commonly cited explanation links it to the Kit-Cat Club, an 18th-century London political club, though other sources have been proposed. Rowntree's marketing helped popularize the product with the Break slogan, which became globally associated with the brand.

Rowntree's was acquired by Nestlé in 1988, and Nestlé markets Kit Kat in most countries outside the United States. In the United States, Kit Kat is produced by The Hershey Company under license from Nestlé.

Varieties and flavors vary by market. The classic milk chocolate bar remains the staple. Other versions include dark chocolate and white chocolate varieties, as well as Kit Kat Chunky in some regions. In addition, many markets feature regional or limited editions, with Japan especially noted for a wide range of flavors such as green tea, strawberry, sakura, and other seasonal offerings. The brand's global presence and local adaptations contribute to its status as a recognizable confectionery icon.
