Kit Kat, one of the most successful brands produced by the Nestlé company, is celebrating its 75th birthday. The name of the iconic chocolate ‘fingers,’ approx. 540 of which are consumed every second around the globe (according to the Guinness Book of Records as of March 2010), dates back to the 17th century and originates from a London-based literary and political club called Kit Kat, the abbreviated name of pastry chef Christopher Catling, the owner of a pie shop where its meetings were held.
