Hello, I'm an expert in the field of confectionery and brand history. Let's dive into the origins and affiliations of the Kit Kat bar.

English Answer:
Kit Kat is a brand of chocolate-covered wafer bar created by Rowntree's of York in the United Kingdom and is currently owned by Nestlé. The brand has been produced internationally under various licenses, and in the United States, it has been produced under a license by the Hershey Company since 1988. However, it's important to note that while Hershey's has the rights to produce Kit Kat in the U.S., the brand itself is still Nestlé's.
