Kit Kat Drops Jingle

NEW YORK Steel workers groove like they are auditioning for Flashdance. A TV news team glides across its studio as if in a 1940s’ Busby Berkeley musical. And a buttoned-down executive break dances on his desk as he prepares for a client meeting. No, this is not The Twilight Zone.

The three 30-second spots are part of Kit Kat’s estimated $15 million campaign, which began running last Monday on network and cable stations. In “Factory,” “Newsroom” and “Office,” busy workers take a bite of the crispy, chocolate wafer and become entranced with “taking a break.”
