Kit Kat has had its fair share of creative marketing campaigns. One of the most memorable is the "Have a break, have a Kit Kat" slogan, which has been around since 1957. This catchy phrase perfectly captured the essence of taking a break and enjoying a snack. Kit Kat has also ventured into unusual partnerships, like creating a Kit Kat pizza in Japan or launching a Kit Kat-themed Android operating system, proving that this brand knows how to keep things interesting.
