Since its introduction into the US in the 1970s, the Hershey's Kit Kat packaging and advertising has differed from the branding used in every other country where it was sold. In 2002, Hershey Kit Kats adopted the slanted [[ellipse]] logo used worldwide by Nestlé, though the ellipse was red and the text white. The US version of "Kit Kat Chunky" is known as "Big Kat".

In the United Kingdom, the product was traditionally wrapped in silver foil and an outer paper band. In 2001 this was changed to flow wrap [[plastic]].<ref>Suzy Bashford [http://www.marketingmagazine.co.uk/article/73773/brand-health-check-kit-kat---nestle-wise-repackage-kit-kat-kit-kat-shed-its-old-style-foil-paper-covering-flow-wrap-tear-strip-convince-consumers-right-move-asks-suzy-bashford "BRAND HEALTH CHECK: Kit kat"] {{Webarchive|url=https://web.archive.org/web/20131029194743/http://www.marketingmagazine.co.uk/article/73773/brand-health-check-kit-kat---nestle-wise-repackage-kit-kat-kit-kat-shed-its-old-style-foil-paper-covering-flow-wrap-tear-strip-convince-consumers-right-move-asks-suzy-bashford |date=29 October 2013 }}, ''Marketing'', 14 June 2001</ref> Foil and paper wrapping is still used for Kit Kats sold as part of a multipack.
